Key Takeaways
- Sciatica is not a condition itself but a symptom caused by compression or irritation of the sciatic nerve, the longest nerve in the body, which runs from the lower spine down the back of each leg.
- With the right rehab plan, most people recover from sciatica without surgery, and physical therapy is considered the gold standard for long-term relief.
- Common causes include herniated or bulging lumbar discs, degenerative disc disease, spinal stenosis, spondylolisthesis, muscle imbalances or piriformis syndrome, and trauma or repetitive strain, so identifying the root cause is key to successful treatment.
- Unlike muscular low back pain, which is usually localized, sciatica radiates pain down one or both legs and involves nerve symptoms such as tingling, numbness, or weakness.
- Side sleeping with a pillow between the knees or back sleeping with a pillow under the knees helps keep the spine aligned, while stomach sleeping should be avoided because it arches the back and worsens pain.
Frequently Asked Questions
What does sciatica feel like?
Sciatica typically causes sharp, shooting pain in the lower back, buttock, thigh, or calf, along with possible numbness or tingling in the leg or foot and weakness in the affected leg. The pain often worsens with sitting, coughing, or sneezing and may ease when lying down or walking short distances.
Can sciatica heal without surgery?
Yes. Most sciatica cases improve with non-surgical treatment, and physical therapy is the gold standard for long-term relief. Surgery is only recommended for severe cases with significant nerve damage or when conservative care fails after 3 to 6 months.
What treatments help relieve sciatica?
Non-surgical options include stretching to relieve nerve compression, core strengthening to stabilize the spine, manual therapy, postural training, nerve gliding techniques, activity modification, ice and heat therapy, and lifestyle or ergonomic adjustments. NSAIDs, electrical stimulation, or ultrasound therapy may also be used under medical supervision or as prescribed.
What daily habits make sciatica worse?
Prolonged sitting without lumbar support, poor posture at desks or while driving, lifting with a rounded back, crossing your legs while seated, and sleeping on a soft, unsupportive mattress can all worsen sciatica. Avoiding these habits can significantly reduce flare-ups and improve recovery.
How is sciatica different from regular back pain?
Sciatica is specifically caused by compression of the sciatic nerve and produces pain that radiates down one or both legs. Muscular low back pain, by contrast, is usually localized and does not involve nerve symptoms like tingling or weakness.
