Persistent Low Back Pain
Back pain that persists beyond about three months — past the point where tissue healing would normally be complete — works differently from acute back pain and responds to different things. The nervous system becomes more sensitive over time, so pain can continue without ongoing tissue damage, and the intensity of pain stops corresponding to the state of the tissue. This is why repeated scans rarely help and frequently make things worse: they show age-related changes present in most pain-free people, and finding them reinforces the belief that the back is damaged. What changes outcomes is graded activity, understanding the mechanism, and addressing sleep, mood, and fear of movement alongside the physical.
Why persistent pain is different
Acute back pain is largely about tissue. Persistent back pain is largely about the nervous system.
Over weeks and months, the pathways carrying pain signals become more sensitive. Less input produces more output. Movements that were fine become painful; the painful area sometimes spreads; pain becomes less predictable and less clearly tied to what you did.
- Pain stops being a reliable guide to damage. Hurting more doesn't mean you've harmed something more. That single reframe changes what people are willing to do.
- Rest stops helping and starts hurting. Deconditioning, stiffness, and reduced confidence all compound.
- Treatments aimed at tissue stop working. Injections, manipulations, and surgery aimed at structures that aren't the problem tend to disappoint, which itself becomes demoralizing.
Why more scans usually don't help
This is where persistent back pain most often goes wrong.
Degenerative findings on imaging are extremely common in people with no pain at all — disc degeneration appears in 37% of pain-free 20-year-olds and 96% of pain-free 80-year-olds, according to a systematic review of 3,110 asymptomatic people.
So a scan will almost certainly find something. In persistent pain, finding it rarely changes treatment and frequently changes behavior for the worse: people told their spine is degenerating move less, and moving less makes persistent back pain worse.
Imaging remains warranted where red flags are present, where there's progressive neurological change, or where surgery is under consideration. → Low back pain — what imaging shows
What changes outcomes
- Graded activity. Increasing what you do by planned amounts rather than by how you feel. → Pacing and activity management
- Exercise. No single type has proven superior. The one you'll keep doing is the right one, and consistency matters more than the choice.
- Pain education. Understanding why pain persists without damage reduces pain and disability in its own right. It's among the better-supported interventions in persistent pain and it's frequently not offered.
- Addressing fear of movement. Avoiding movements believed to be dangerous maintains both the sensitivity and the disability. Graded exposure — doing the feared movement in a controlled, progressive way — is the treatment.
- Sleep. Poor sleep lowers pain thresholds measurably. It's one of the more tractable targets.
- Mood. Depression and anxiety both amplify pain and are both treatable. Addressing them is not conceding the pain is psychological.
- Multidisciplinary programs — combining physical, educational, and psychological components — have the strongest evidence for persistent pain.
What generally doesn't help long-term: repeated imaging · passive treatments alone · long-term opioids, which have poor evidence in persistent back pain and meaningful harms · surgery for non-specific back pain.
Goals worth setting
Sit through a movie · Drive an hour without stopping · Return to work full-time · Play with my grandchildren on the floor · Do the weekly grocery run in one trip
Reduce pain · Improve lumbar range of motion
Frequently asked questions
Why hasn't my back pain gone away?
Beyond about three months, pain is less about tissue and more about a nervous system that has become more sensitive. The pain is real; the tissue is often no longer the explanation.
Should I get another scan?
Usually not. Scans in persistent back pain nearly always find age-related changes that are present in most pain-free people, rarely change treatment, and frequently make people more fearful of moving.
Does hurting mean I'm damaging something?
In persistent pain, generally not. Pain stops being a reliable guide to tissue damage, which is why graded activity is safe even when it's uncomfortable.
Is my pain psychological?
No. Psychological factors influence pain — as they influence all pain — but persistent pain involves genuine changes in nervous system processing. Both things are true, and they aren't the same claim.
What actually helps?
Graded activity, exercise you'll keep doing, pain education, addressing fear of movement, and attention to sleep and mood. Multidisciplinary programs combining these have the strongest evidence.
Should I consider surgery?
For non-specific persistent back pain, surgery is generally not indicated. It's considered where there's nerve compression with progressive neurological signs or specific pathology.
Will I always have this?
Many people improve substantially. Function frequently improves before pain does, and for some the pain reduces considerably over time with the right approach.
