The large majority of back pain eases within a few weeks. In a smaller share, though, the pain becomes persistent — and what decides who that happens to is often not the change seen on a scan, but how we respond to the pain: fear of movement, avoidance, beliefs, and mood. The pain is real; this article is about what keeps it going — and what can be done about it.
Let us start with the most important point: if pain has been with you for months, it does not mean it is "in your head," nor that you are exaggerating. The pain is real. But chronic pain works differently from acute pain: the longer it lasts, the more it is sustained not only by the original tissue cause, but by how the nervous system, movement and daily life organise around it. So the question is not whether it is "real," but what keeps it going — because that can be changed.
A few factors reliably go together with back pain becoming persistent. They are found not on the scan, but in our relationship to the pain (the literature calls them "warning," or yellow-flag, factors):
These are not character flaws or signs of weakness — they are understandable responses to pain. But if they take hold, they themselves keep the problem going.
The best-documented pattern is the fear-avoidance cycle. Pain creates fear of movement; fear leads us to avoid load; avoidance weakens the muscles, narrows the range of motion, reduces stamina; and the weakened body hurts even more easily — and the cycle starts again. The good news: the cycle can be broken. Not complete rest, but a gradual, safe return to movement is what leads out of it.
This echoes what I have written separately about scan reports: imaging on its own does not tell us in whom the pain will become lasting. People without symptoms often have "changes" on their images, and the severity on the scan does not precisely predict how the complaint will develop. In becoming chronic, the pain-related factors above play an important role — so they deserve at least as much attention as the picture.
The good news is that these factors can be influenced — and where they are addressed in time, the outcome improves more often. What helps in practice:
If the pain does not improve after six weeks of appropriate, targeted treatment, it is worth investigating — and if any alarming sign accompanies it, it cannot wait (a separate guide covers this). Otherwise, persistent back pain most often settles conservatively, with the approach described above.
This guide does not replace a medical examination.
If your complaint has persisted for weeks and you would like to think through the next step with a specialist, book an appointment — together we will look at what is keeping it going, and what leads out of it.
