Rotator Cuff Pain and Tears
The complete guide for adults: what the rotator cuff is, how cuff pain differs from a tear, why it hurts at night, when imaging helps, what exercise, injections and surgery can each do, exercises to start with, and how long recovery takes.
- Expert Reviewed
- Evidence Based
- Patient Focused
The rotator cuff is four muscles whose tendons cover the top of the arm bone, lifting and rotating the arm and holding the ball of the shoulder in its socket.1,2 Rotator cuff problems range from irritated tendons (tendinopathy, bursitis, impingement) to partial and full-thickness tears, and they are the most common cause of shoulder pain.3,4 Many tears come with age and cause no pain at all.1,5 Nonsurgical treatment, built around exercise, relieves pain and improves function in most people; surgery is for acute injuries, some active people, and pain and weakness that do not improve.1,2
Most rotator cuff pain, including many tears that come with age, improves without surgery: an exercise program is the first treatment, and in trials of degenerative tears it did about as well as repair over one to two years.1,6,7 Pain at night, especially lying on that shoulder, is typical.1 Sudden weakness after a fall needs a prompt check, and shoulder pain with chest pain or shortness of breath needs 911.1,8
Key takeaways
- The rotator cuff is four muscles, the supraspinatus, infraspinatus, subscapularis and teres minor; most tears are in the supraspinatus.1,2
- Cuff changes are a normal part of aging: in pooled studies they rose from about 10% of people aged 20 and younger to 62% of those 80 and older, with or without pain.5
- The AAOS reports that nonsurgical treatment relieves pain and improves function in about 80% to 85% of patients.1
- In a US cohort of 452 people with full-thickness tears that were not caused by an injury, about 75% treated with a physical therapy program had not chosen surgery two years later.9
- Shaving bone to make room for the tendons (subacromial decompression) did no better than placebo surgery in two trials, and a BMJ guideline panel recommends against it.10,11,12
- Surgery is recommended when pain or weakness persists after a dedicated course of therapy, for active people who work or play overhead, and sometimes for complete tears caused by an injury; full rehabilitation can take up to a year.2
What is the rotator cuff, and what does it do?
The shoulder is a ball-and-socket joint: the head of the upper arm bone (humerus) sits in a shallow socket on the shoulder blade (scapula).2 The rotator cuff is a group of four muscles that start on the shoulder blade and come together as tendons, forming a cover over the head of the humerus.1,2 It lifts and rotates the arm and keeps the ball centered in its socket while you move.2
Between the cuff and the bony roof of the shoulder (the acromion) is a lubricating sac, the bursa, which lets the tendons glide; when the tendons are damaged, the bursa can become inflamed and painful too.1
| Muscle | What to know |
|---|---|
| Supraspinatus | Supports the shoulder joint; most tears occur in its tendon.1,14 |
| Infraspinatus | Supports the shoulder joint and is the main muscle worked by external rotation (turning the arm outward) exercises.14 |
| Teres minor | Works with the infraspinatus in external rotation exercises.14 |
| Subscapularis | At the front of the shoulder; worked by internal rotation (turning the arm inward) exercises.14 |
Rotator cuff tears are a common cause of shoulder pain and disability in adults: almost 2 million people in the U.S. see their doctors for them each year.1
Rotator cuff pain vs. a rotator cuff tear: what is the difference?
One umbrella term, rotator cuff related shoulder pain, covers a spectrum that runs from impingement and tendinopathy to symptomatic partial and full-thickness tears.3 The labels describe what is happening in the tissue, but they do not map neatly onto how much it hurts: many tears cause no pain at all.1,5
- Tendinitis or tendinopathy
Irritation of the cuff tendons; MedlinePlus notes it is also called impingement syndrome.13,15
- Bursitis
Inflammation of the bursa between the cuff and the acromion.15
- Impingement
The space under the acromion narrows when you raise the arm, so the bone can rub on the tendon and bursa.15
- Partial-thickness tear
The tear goes only part way through the tendon, which stays attached to the bone but thinner than normal.1
- Full-thickness tear
Part or all of the tendon is detached from the bone; a complete one leaves essentially a hole in the tendon.1
| Feature | Cuff pain (tendinopathy, bursitis) | Rotator cuff tear |
|---|---|---|
| How it starts | Gradually with overhead use or repetitive work, or after a minor injury15 | Suddenly after a fall or heavy lift, or slowly as the tendon wears1 |
| Where it hurts | Front or side of the shoulder, stopping above the elbow13,15 | Front or side of the shoulder, traveling down the side of the arm2 |
| Strength | Weakness and lost motion can develop as it progresses15 | Weakness lifting or rotating the arm is common1 |
| Night pain | Typically worst at night15 | Pain at rest and at night, especially lying on that side1 |
| First treatment | Nonsurgical in most cases15 | Nonsurgical for most degenerative tears; surgery sooner for some acute tears1,2 |
Tears are also described by cause. An acute tear follows an injury such as a fall on an outstretched arm, sometimes with a dislocated shoulder or broken collarbone; a degenerative tear comes from slow wear of the tendon with age, and most tears are this kind.1
Rotator cuff tear symptoms: why does it hurt at night?
Pain is usually felt in the front or side of the shoulder and can travel down the side of the arm.2 Early on it may be mild and appear only when you reach overhead, such as into a high cabinet; over time it can be present at rest and stop responding to medicine.1
Common signs of a rotator cuff problem
- Pain at rest and at night, especially lying on the affected shoulder1
- Pain when lifting and lowering the arm, or with particular movements1
- Weakness when lifting or rotating the arm1
- A crackling sensation (crepitus) when moving the shoulder in certain positions1
- Trouble combing your hair, putting on a seatbelt or reaching behind your back1,15
A tear from a fall usually causes intense pain, sometimes with a snapping sensation and immediate weakness.1 A tear that develops slowly often has no clear starting point, because the pain, weakness and stiffness worsen gradually.13 Some tears are not painful but still weaken the arm.1
Why is rotator cuff pain worse at night?
Night pain is one of the most consistent features: rotator cuff tears often cause pain at night that can wake you, while daytime pain is more tolerable and comes with particular movements.13 Lying on the painful side adds to it.1,2 With tendinitis too, pain is typically worst at night, and as it progresses it can affect your sleep.15
How should you sleep with rotator cuff pain?
Lie on the side that is not painful or on your back, and try resting the painful shoulder on a couple of pillows.16 Physical therapists also advise against sleeping with the arm stretched overhead or lying on the shoulder.17
Who gets rotator cuff problems, and what causes them?
Most tears come from wear of the tendon over time, which happens naturally with age and is often painless; others follow an injury.1 Rotator cuff pain is common in both young athletes and older people.15
- Age over 40
Because most tears come with normal wear, people over 40 are at greater risk; most tears in young adults follow an injury such as a fall.1
- Overhead work
Painting, carpentry, construction and other work with the arms overhead.1,15
- Overhead sport
Swimming, baseball pitching, tennis, volleyball and lifting weights overhead.13,15
- Repetitive lifting
Repeating the same shoulder motions stresses the cuff muscles and tendons, in jobs and routine chores as well as sport.1
- Long static positions
Keeping the arm in one position for long periods, such as computer work or hairstyling, and sleeping on the same arm each night.13
- Posture
Poor posture over many years; a forward head and shoulders changes how the shoulder blade sits.13,17
- Reduced blood supply
The tendons’ blood supply decreases with age, which impairs repair; smoking can decrease it further.1,17
- The other shoulder
A degenerative tear in one shoulder makes a tear in the other more likely, even when that shoulder does not hurt.1
How common are rotator cuff tears?
Very common, and more so with every decade. A pooled analysis of 30 studies and 6,112 shoulders found cuff abnormalities in 9.7% of people aged 20 and younger and in 62% of those aged 80 and older, rising similarly in people with and without symptoms.5 The authors concluded that cuff degeneration can be considered a common part of normal aging.5
When should you see a doctor for rotator cuff pain?
Contact your provider if shoulder pain keeps going or does not improve with treatment.13 Early treatment can stop symptoms from getting worse and get you back to your routine sooner.1 Some shoulder pain needs care sooner:4
| When | What it is for |
|---|---|
| Now: call 911 | Sudden pressure or crushing pain in the shoulder, especially spreading from the chest to the jaw, arm or neck, or with shortness of breath, dizziness or sweating.4,8 |
| Now: the emergency room | A severe injury that leaves the shoulder very painful, swollen, bruised or bleeding.4 |
| Soon: your doctor | A fall or heavy lift followed by a snapping sensation and immediate weakness, which can be an acute tear.1 |
| Soon: your provider | Shoulder pain with fever, swelling or redness, or red or blue skin.4 |
| After 2 to 4 weeks | Pain that has not improved with home treatment.4 |
| Anytime: a physical therapist | You can see a physical therapist directly for an evaluation; every state allows some form of direct access.17,18 |
Who treats rotator cuff problems?
If your primary care provider has made the diagnosis, an orthopedic surgeon can review both surgical and nonsurgical options and start treatment.2 Physical therapists evaluate and treat rotator cuff tears, and they work with your orthopedist when deciding whether surgery is needed.17
How is a rotator cuff tear diagnosed?
With your history and an examination; imaging is added when it would help confirm the diagnosis.1,2
- Your history. Your symptoms, how they began, and your medical history.1
- Tenderness. Your doctor presses on different parts of the shoulder to find tender spots.15
- Range of motion. You move your arm in several directions; if pain stops you, the doctor may move the arm for you to judge how stiff it is.1,15
- Strength tests. Your arm strength is tested in different positions and movements.1
- A combination of tests. No single test settles it; the AAOS guideline finds that several tests together are more accurate than any one.19
- Your neck. The doctor may examine your neck to rule out a pinched nerve or arthritis as the source of pain.1
A physical therapist examines the same way, raising your arm, moving it out to the side and asking you to resist at set angles, and can refer you for imaging when needed.17
Do you need an MRI for rotator cuff pain?
Not usually to begin with. X-rays are usually the first test: they cannot show the cuff, so they are often normal, but they rule out other causes such as arthritis.1 An MRI or ultrasound shows the tendons and the location and size of a tear, and an MRI also gives a sense of how old a tear is from the quality of the muscle.1 The AAOS guideline describes MRI, MRA, CT and ultrasound as useful additions to the clinical exam and X-rays.19
Imaging has a catch: cuff abnormalities are so common in people without symptoms that a finding on a scan may not be the cause of your pain.5 It is most useful when surgery is being considered: the size of the tear and the quality of the surrounding tissue are among the things surgeons weigh.1,20 An ultrasound can be quicker to schedule than an MRI, but its accuracy depends on the skill of the person doing the scan.1
Is it a rotator cuff problem or frozen shoulder?
The two are easy to confuse, because both cause shoulder pain that is worse with reaching. The clearest difference is movement when someone else lifts the arm: frozen shoulder’s hallmark is being unable to move the shoulder either on your own or with someone else’s help.21
| Feature | Rotator cuff problem | Frozen shoulder |
|---|---|---|
| Main complaint | Pain with lifting and lowering, and weakness lifting or rotating the arm1 | Severe pain and a shoulder that will not move21 |
| Who gets it | More common over 40, and in overhead work and sport1 | Most often people aged 40 to 60, women more than men21 |
| Imaging | MRI or ultrasound shows the tear’s location and size1 | MRI and ultrasound are not required to diagnose it21 |
| Usual course | Tendinitis often settles over weeks or months with rest, exercise and self-care13 | Gets better over time without surgery, but may take up to 3 years21 |
Our frozen shoulder guide covers its stages and treatment. Pain can also come from the neck: referred pain is usually present at rest and does not get worse when you move the shoulder, and pain that runs past the elbow into the hand points to a nerve.4,13 The neck pain guide covers that side.
Rotator cuff treatment: what works and what doesn’t
Treatment aims to reduce pain and restore function, and the best plan depends on your age, activity level, general health and the type of tear.1 For most people it starts without surgery; the table sets out what each option can and cannot do.1,15
| Treatment | What it involves | The evidence |
|---|---|---|
| Exercise and physical therapy | Stretching to restore motion, then strengthening of the cuff and shoulder-blade muscles.1,15 | First line The AAOS guideline (strong) finds both therapy and surgery improve small to medium full-thickness tears.19 |
| Activity changes and relative rest | Avoiding the overhead movements that bring on the pain.1,15 | Recommended Part of the AAOS nonsurgical plan, which helps about 80% to 85% of patients.1 |
| Anti-inflammatory medicines (NSAIDs) | Ibuprofen or naproxen for pain and swelling.1 | Pain relief Eases pain; tell your provider if you take them every day.16 |
| Ice and heat | Ice 20 minutes at a time, 3 to 4 times a day; moist heat to loosen the shoulder.16 | For comfort Used to cut swelling and ease pain.16 |
| Steroid (cortisone) injection | A steroid with a local anesthetic, usually into the bursa under the acromion.15 | Short term One injection can be considered for short-term pain and function (moderate); repeated injections may weaken the cuff (limited).19 |
| Hyaluronic acid injection | An injection of hyaluronic acid.19 | Limited May be considered only where there is no tear (limited evidence).19 |
| Platelet-rich plasma (PRP) | Platelet-rich plasma injected into the shoulder.19 | Not supported Routine use is not supported for tendinopathy or partial tears, and may not be indicated for full-thickness tears.19 |
| Prolotherapy | Prolotherapy injections.19 | Not recommended Not recommended for full-thickness tears (strong).19 |
| Subacromial decompression | Keyhole surgery that removes bone spurs and the bursa to make more space.15 | Not recommended No better than placebo surgery; a guideline panel recommends against it.12,22 |
| Rotator cuff repair | Reattaching the torn tendon to the bone, usually by arthroscopy.20 | Selected tears For acute tears, persistent pain and weakness, and some active people; in one trial repair did better at 10 and 15 years.2,23,24 |
Can a torn rotator cuff heal without surgery?
The tendon itself usually does not grow back to the bone, but the shoulder often gets better anyway. The AAOS puts it plainly: most tears cannot heal on their own, yet you can often achieve good function without surgery, because many other muscles and tendons help move the arm.2 A tear that has pulled back (retracted) from the bone does not heal on its own.13
The trials point the same way for tears that come with age:6,7
| Study | What it found |
|---|---|
| Finnish trial, 180 shoulders | Physical therapy alone, physical therapy with acromioplasty, and repair did not differ at two years; the authors call therapy a reasonable first treatment in older patients.6 |
| Cochrane review, 9 trials, 1,007 people | Repair may give little or no clinically important benefit over exercise-based care at one year, for mostly small degenerative supraspinatus tears.7 |
| US MOON cohort, 452 people | Pain and function improved by 6 and 12 weeks of a set therapy program, and about 75% had not chosen surgery at two years.9 |
| Norwegian trial, 103 people | Small at first, the advantage of repair grew: at 10 years, 9.6 points on the Constant shoulder score, and at 15 years 11.8; 15 of 51 in the therapy group had crossed over to surgery.23,24 |
The catch is time. An unrepaired tear can enlarge: in people with a painless degenerative tear followed for about five years, 49% of tears grew, and growth went with new pain.25 In the Norwegian trial, tears treated with therapy alone grew on average from 16.2 to 31.6 millimeters over 15 years.24 The AAOS guideline (strong) therefore says therapy improves symptoms with full-thickness tears, but the tear and its muscle may worsen over 5 to 10 years without surgery.19
For most people that means starting with exercise and keeping an eye on the shoulder: worsening pain with falling strength may mean the tear is getting larger, and is a reason to go back to your doctor.2 The Cochrane findings may not apply to tears from an injury, large tears or young people, and the AAOS more often recommends surgery for active, younger people and some acute tears.2,7
What decides who ends up having surgery?
Not only the tear. In the MOON cohort, the strongest predictor of choosing surgery was a patient’s low expectation that physical therapy would work, more than the symptoms or the size of the tear.26 Higher activity levels and not smoking also predicted surgery.26
Physical therapy for rotator cuff pain: what to expect
A physical therapist works on range of motion, muscle strength and coordination, and may teach you to change how you do things so the shoulder takes less stress.17 The goal is to function as well as possible with little or no pain.27
- The evaluation. How your shoulder and shoulder blade move during activities, your posture, your range of motion, which muscles are weak or stiff, and which movements bring on the pain.27
- Calming the pain. Activity changes, ice or heat, and medicine as needed while the shoulder settles.15,16
- Getting motion back. Passive exercises first, in which the therapist moves the arm or you use your good arm to move it.16
- Strengthening. Once pain improves, exercises for the cuff and shoulder-blade muscles, with lower weights and higher repetitions because the cuff muscles are small.15,16
- Posture and technique. Correct shoulder posture and ways to move for everyday tasks or sport.27
- Return to activity. A gradual return once there is no pain at rest or with activity, full strength, and normal movement of the shoulder and shoulder blade.16
How long is physical therapy for a rotator cuff injury?
There is no single length. In the MOON cohort, people were reassessed at 6 and 12 weeks, and those who went on to surgery usually decided in that window.9 The AAOS conditioning program runs 4 to 6 weeks unless your doctor or therapist says otherwise, then can continue 2 to 3 days a week as maintenance.14 With tendinitis, recovery can take several weeks to months.15
Does physical therapy really help a rotator cuff?
It helps most people, but the evidence has honest limits. Exercise-based care has done about as well as repair for degenerative tears over one to two years, and, on low-quality evidence, about as well as injections and decompression surgery for cuff pain.6,7,28 Yet the one high-quality trial comparing manual therapy and exercise with a placebo found no clinically important difference at 22 weeks.28 Mild soreness after treatment is the usual side effect.28
Rotator cuff exercises to do at home
Talk to your doctor or physical therapist before starting shoulder exercises, and ask which are safe for you.1,14 Warm up first with 5 to 10 minutes of walking or a stationary bike.14 You should not feel pain during an exercise; if one hurts during or afterward, change how you do it or lower the resistance.14,27 These six come from the AAOS rotator cuff and shoulder conditioning program.14
Pendulum
A gentle start: the arm hangs and swings freely.14
- Lean forward and place one hand on a counter or table for support.
- Let your other arm hang freely at your side.
- Gently swing the arm forward and back, then side to side, then in a circle.
The AAOS program: 2 sets of 10, 5 to 6 days a week. Do not round your back or lock your knees.14
Standing row
Works the middle and lower trapezius, felt at the back of the shoulder and upper back.14
- Tie a 3-foot loop of elastic band and attach it to a doorknob or other stable object.
- Stand holding the band with your elbow bent and at your side.
- Keep your arm close to your side and slowly pull your elbow straight back, then slowly return.
The AAOS program: 3 sets of 8, 3 days a week, building to 3 sets of 12. Squeeze your shoulder blades together as you pull.14
External rotation with a band
Strengthens the infraspinatus and teres minor, which turn the arm outward.14
- Attach a 3-foot loop of elastic band to a doorknob or other stable object.
- Stand holding the band with your elbow bent and at your side.
- Keeping your elbow close to your side, slowly rotate your arm outward, then slowly return.
The AAOS program: 3 sets of 8, 3 days a week, building to 3 sets of 12.14
Internal rotation with a band
Strengthens the subscapularis at the front of the shoulder.14
- Attach a 3-foot loop of elastic band to a doorknob or other stable object.
- Stand holding the band with your elbow bent and at your side.
- Keep your elbow close to your side and bring your arm across your body, then slowly return.
The AAOS program: 3 sets of 8, 3 days a week, building to 3 sets of 12. Keep your elbow pressed into your side.14
Scapula setting
Works the middle trapezius and serratus, felt at the shoulder blade.14
- Lie on your stomach with your arms by your sides, a pillow under your forehead if you need one.
- Gently draw your shoulder blades together and down your back as far as you can.
- Ease about halfway off from this position and hold for 10 seconds, then relax.
The AAOS program: 10 repetitions, 3 days a week. Do not tense your neck.14
Side-lying external rotation
Strengthens the muscles that turn the arm outward, with a light hand weight.14
- Lie on your unaffected side, with that arm under you cradling your head.
- Hold your injured arm against your side with the elbow bent to 90 degrees.
- Keep your elbow against your side and slowly rotate the arm to raise the weight upright, then lower it to a count of 5.
The AAOS program: 2 sets of 10 with about 1 to 2 pounds, 3 days a week. Do not let your body roll back.14
Keep the weights light: the cuff muscles are small, so strengthening should use smaller weights and more repetitions.27 Your therapist may add wall push-ups, isometric exercises or stretches for the back of the shoulder.27
What should you avoid with rotator cuff pain?
- Pushing through pain
Keep going despite increasing pain with a tear and you may cause further damage.1
- Long stretches with the arms overhead
Use a stool or ladder rather than working above shoulder level for a long time.16
- Heavy loads away from the body
Lift and carry close to your body, not out in front or overhead.16
- A bag on one shoulder
Do not carry a backpack or purse over just one shoulder.16
- The same movement for hours
Take regular breaks from anything you do over and over.16
- Sport before you are ready
Wait until there is no pain at rest or with activity, and your strength and movement are back.16
Do cortisone shots or PRP help rotator cuff pain?
A steroid injection can help when rest, medicine and physical therapy have not relieved the pain. It is usually given into the bursa beneath the acromion, with or without ultrasound guidance.1,15 On average, an injection relieves pain in about two-thirds of patients for at least 3 months, but there is no way to know how long the effect will last in your case.1
The AAOS guideline supports a single injection with a local anesthetic for short-term improvement in pain and function, and injectable anti-inflammatory medicine for people who cannot have steroids.19 It warns, on limited evidence, that multiple injections may compromise the cuff and affect a later repair.19 For cuff tendinopathy specifically, a review of injection trials found the short-term benefit of steroid injections unclear; at the elbow, the early benefit reversed at 6 and 12 months.29 Compared with manual therapy and exercise, injections gave similar pain and function from 4 weeks to 12 months, though more people rated their treatment a success with an injection up to 11 weeks (low-quality evidence).28
- Platelet-rich plasma (PRP)
Routine use is not supported for tendinopathy or partial tears, and may not be indicated for full-thickness tears.19
- Hyaluronic acid
May be considered for cuff problems without a tear, on limited evidence.19
- Prolotherapy
Not recommended for full-thickness tears (strong recommendation).19
When do you need rotator cuff surgery?
Continued pain that does not improve with nonsurgical treatment is the main reason.1 Other signs that surgery may be a good option:1
Signs surgery may be worth discussing
- Symptoms that have lasted 6 to 12 months1
- Pain at rest or at night that has not improved with a specific physical therapy program over 3 to 4 months30
- A large tear, more than 3 cm, with good-quality tissue around it1
- Significant weakness and loss of function1
- A tear caused by a recent, acute injury1
- An active life with overhead work or sport, such as pitching, swimming, tennis, construction or painting2
For a partial tear, surgery may be only a trimming (debridement); a full-thickness tear is stitched back to the bone.2 Most repairs are done by arthroscopy, through small incisions, as same-day surgery.20 For high-grade partial tears that have not improved with therapy, the AAOS guideline (strong) finds repair can improve outcomes.19
Results are better when the tendon heals: healed repairs do better than both physical therapy and repairs that did not heal.19 The chance of a good result falls with poor tissue quality, large or massive tears, age over 65, smoking, and not following the rehabilitation plan.20 A re-tear is possible with every type of repair, though people who re-tear usually do not have more pain or worse function.20
Does bone spur surgery (subacromial decompression) help?
No more than a placebo operation. In the UK CSAW trial of 313 people who had already tried exercise and a steroid injection, decompression did no better than arthroscopy alone, and both surgical groups’ small edge over no treatment was not clinically important.10 A Finnish placebo-controlled trial of 210 people found the same at two years.11 A Cochrane review rates the evidence of no clinically important benefit as high certainty, and a BMJ guideline panel makes a strong recommendation against the operation for shoulder pain lasting more than 3 months.12,22
How long does rotator cuff recovery take?
It depends on what is wrong and how it is treated. Without surgery, many people improve within weeks to months; after a repair, recovery is measured in months.15,20
| Situation | Typical time |
|---|---|
| Tendinitis with rest, exercise and self-care | Weeks or months13 |
| Therapy for a full-thickness tear | Improvement by 6 and 12 weeks in the MOON cohort9 |
| Sling after a repair | Usually 4 to 6 weeks20,30 |
| Moving the arm yourself after a repair | Active exercise after 4 to 6 weeks; strengthening from 8 to 12 weeks20 |
| Useful motion and strength after a repair | Most people by 4 to 6 months20,30 |
| Sport, heavy lifting or strenuous work | A modified return may not begin until 4 months; a full return may take 9 months to a year17 |
Even with a good repair, the muscles around the shoulder stay weak, and complete rehabilitation can take several months or up to a year.2 After surgery, your surgeon decides when it is safe to move the arm and how long the sling stays on, because the repair needs protecting while the tendon heals.2,20 For small repairs, the AAOS guideline finds one session of instruction plus a home program works as well as supervised visits for the same home exercises.19
Rotator cuff pain relief at home
Pain relief, using the shoulder carefully and regular exercises can all ease symptoms.16
Looking after a sore rotator cuff at home
- Ice wrapped in a towel, 20 minutes at a time, 3 to 4 times a day when it hurts16
- Moist heat, such as a warm shower or heat pack, to loosen a sore shoulder16
- Ibuprofen or naproxen if you need it, telling your provider if you take it every day16
- Good sitting posture, with your head over your shoulders and a pillow behind your lower back16
- Things you use every day stored where you can reach them easily, and your phone kept close16
- Reaching with your thumb pointing up16
Does Medicare cover physical therapy for a rotator cuff injury?
Yes, when it is medically necessary. Medicare Part B covers outpatient physical therapy, and a doctor or another provider such as a nurse practitioner or physician assistant must certify that you need it.31
| Coverage | What to know |
|---|---|
| Original Medicare, Part B | After the Part B deductible you pay 20% of the Medicare-approved amount, with no yearly limit on medically necessary outpatient therapy.31 |
| The 2026 KX threshold | Once therapy costs pass $2,480 for physical therapy and speech-language pathology combined, or a separate $2,480 for occupational therapy, the clinic adds the KX modifier to confirm the therapy is medically necessary.32 |
| Targeted medical review | Claims can be reviewed once costs reach $3,000.32 |
| Medicare Advantage | Plans must cover all medically necessary services Original Medicare covers, but may require prior authorization, a referral or in-network providers.33 |
| Seeing a therapist first | Every state allows some form of direct access to a physical therapist, though an insurance policy or state law may still require a referral.17,18 |
Rotator cuff myths and facts
- Myth: a tear on the MRI explains the pain
Cuff abnormalities are common in people with no symptoms, which makes it hard to tell whether one is the cause.5
- Myth: a torn rotator cuff always needs surgery
About 75% of people with nontraumatic full-thickness tears treated with a therapy program had not chosen surgery at two years.9
- Myth: exercise cannot help a full-thickness tear
The AAOS guideline (strong) finds patient-reported outcomes improve with physical therapy in full-thickness tears.19
- Myth: shaving the bone spur makes room and fixes the pain
Subacromial decompression did no better than placebo surgery in two trials.10,11
- Myth: a cortisone shot heals the tendon
An injection relieves pain for a time, and multiple injections may compromise the cuff.1,19
- Myth: if it is degenerative, it cannot change
Degenerative tears can enlarge over the years, and enlargement goes with new pain.25
Rotator cuff recovery goals worth setting
Comb or wash my hair · Put on a coat or fasten a seatbelt · Reach into a high cabinet · Sleep through the night · Get back to my tennis serve
Strengthen the rotator cuff · Improve range of motion
The first line names what a rotator cuff problem takes away, from combing your hair to reaching a high shelf.1,15 If your goals read like the second line, ask for them in daily-life terms: the aim of therapy is to function as well as possible with little or no pain.27
How do you find a physical therapist for rotator cuff pain?
Every physical therapist is trained to treat rotator cuff tears. You may prefer one experienced with muscle, bone and joint problems, at a clinic with an orthopedic focus or experience with athletes, or one who is a board-certified clinical specialist or has completed a residency or fellowship in orthopedic or sports physical therapy.17 Ask about their experience with rotator cuff tears, and be ready to describe your symptoms and what makes them worse.17

Frequently Asked Questions
How many rotator cuff tendons are there?
Four. The rotator cuff is four muscles, the supraspinatus, infraspinatus, subscapularis and teres minor, whose tendons join to cover the head of the upper arm bone.2 Most tears are in the supraspinatus tendon.1
Can a torn rotator cuff heal without surgery?
The tendon usually does not reattach on its own, but the shoulder often recovers good function without surgery.2 In a US cohort, about 75% of people with nontraumatic full-thickness tears treated with physical therapy had not chosen surgery two years later.9
Can physical therapy make a torn rotator cuff worse?
Exercise is the first treatment for most tears, and the AAOS guideline finds outcomes improve with physical therapy in full-thickness tears.19 Pain during or after an exercise is a signal to change it or lower the resistance, and pushing on through increasing pain with a tear can cause further damage.1,27 Some unrepaired tears grow over the years, so tell your clinician if your strength is falling.2,25
How do I know if I need surgery on my rotator cuff?
Signs include pain that has not improved after 6 to 12 months or after a dedicated course of physical therapy, significant weakness, a large tear with good tissue, or a tear from a recent injury.1,2 People who use the arm overhead for work or sport are more often advised to have surgery.2
Is it a rotator cuff tear or tendinitis?
Both cause pain in the front or side of the shoulder that is worse reaching overhead and at night.1,15 Weakness lifting or rotating the arm, or intense pain with a snap after a fall, points more to a tear; an examination, with imaging when needed, tells them apart.1
Do I need an MRI for shoulder pain?
Not usually at first. X-rays come first to rule out other causes, and an MRI or ultrasound is added when a tear needs confirming.1,19 Cuff changes are common in people without pain, so a scan finding is not always the cause.5
Does a cortisone shot help rotator cuff pain?
Often, for a while: injections relieve pain in about two-thirds of patients for at least 3 months.1 The AAOS guideline supports a single injection for short-term relief and warns that multiple injections may weaken the cuff.19
How long is recovery after rotator cuff surgery?
Most people wear a sling for 4 to 6 weeks and have useful motion and strength by 4 to 6 months.20 A full return to sport or heavy work may take 9 months to a year.17

“Each year, almost 2 million people in the U.S. visit their doctors because of rotator cuff tears”; the rotator cuff is “a group of four muscles that come together as tendons to form a covering around the head of the humerus” and “helps to lift and rotate your arm”; “Most tears occur in the supraspinatus tendon”; partial and full-thickness tears; injury (acute) and wear (degeneration), “Most tears are the result of a wearing down of the tendon that occurs slowly over time”; more common in the dominant arm, with a greater likelihood of a tear in the other shoulder; the blood supply decreases with age; “people over 40 are at greater risk”; overhead work and sports; symptoms include “Pain at rest and at night, especially if you are lying on the affected shoulder,” weakness lifting or rotating the arm and crepitus; sudden tears cause “intense pain. There may be a snapping sensation and immediate weakness”; “some rotator cuff tears are not painful”; X-rays first, usually normal; MRI or ultrasound show the location and size of a tear, ultrasound accuracy “depends on the quality of the technician”; “A rotator cuff tear can get larger over time”; “In about 80 to 85% of patients, nonsurgical treatment relieves pain and improves function”; cortisone gives “pain relief in about two-thirds (about 67%) of patients for a period of at least 3 months,” with risks from repeated, long-term injections; signs surgery may be a good option: symptoms for 6 to 12 months, a tear larger than 3 cm with good tissue, significant weakness, a recent acute injury. - American Academy of Orthopaedic Surgeons, OrthoInfo.
