The injury healed months ago. The scan came back “unremarkable.” You’ve been told there’s nothing seriously wrong. And yet the pain is still there — and some days it’s as bad as it ever was. If that’s you, the most useful thing to understand is this: pain that outlasts the injury usually isn’t a sign of ongoing damage. It’s a sign the nervous system itself has become sensitised.
This isn’t “the pain is in your head,” and it isn’t you imagining it. The pain is completely real. But the cause has shifted from the tissue to the system that processes pain — and that changes everything about how you treat it.
How pain is supposed to work
Normally, pain is a useful alarm. You injure a tissue, sensors send a danger signal up to the spinal cord and brain, the brain decides it’s worth protecting, and you feel pain. The tissue heals over days to weeks, the signals settle, and the pain fades. The alarm did its job and switched off.
Most tissues heal within a fairly predictable window — a matter of weeks to a few months, even for significant injuries. So when pain is still going strong well beyond that, the healed tissue usually isn’t the problem anymore. Something else is keeping the alarm on.
What sensitisation actually is
When pain signals fire for long enough, the nervous system can become better and better at producing pain — a process called central sensitisation. Think of it as the volume knob on the alarm being turned up, and then getting stuck there.
Practically, a sensitised system does a few characteristic things:
- Turns up the volume — things that should feel mildly uncomfortable feel genuinely painful, because the system amplifies the signal.
- Lowers the threshold— movements, positions, or pressures that shouldn’t hurt at all start to trigger pain, because the alarm is now set to go off at a much lower level of input.
- Spreads — pain can become more widespread or harder to pin to one spot, because the sensitisation is in the system, not a single tissue.
- Becomes unpredictable — flaring with stress, poor sleep, or bad days rather than tracking neatly with what you physically did.
None of that means you’re fragile or that something is being missed. It means the problem has become the sensitivity of the system, not damage in the tissue.
What feeds it
Sensitisation is driven and maintained by more than just the original injury:
- Time — the longer pain persists, the more entrenched the pattern
- Poor sleep — one of the biggest amplifiers of pain sensitivity
- Stress and worry about the pain — the nervous system treats fear as a reason to keep protecting
- Avoiding movement — the less you move, the more threatening movement becomes to the system, and the more it guards
- Being told something is badly wrong — alarming language and scary scan reports keep the alarm justified
That last one matters. People are often handed frightening interpretations of normal, age-related scan findings — “degeneration,” “bulging,” “wear and tear.” These findings are extremely common in people with no pain at all, but hearing them can wind the system tighter.

Why exercises or rest alone often don’t fix it
Here’s why so much standard treatment underperforms for persistent pain. If you treat it as a pure tissue problem — just load it, just strengthen it, just stretch it — you’re often loading a system that’s already on high alert, which can flare it. And if you go the other way and rest completely, the system becomes more protective and the sensitivity gets worse.
Persistent pain needs an approach aimed at the sensitised system, not just the tissue: calming the system down, then gradually and confidently rebuilding tolerance so the alarm learns that movement is safe again. More on why timing and order matter in treatment →
What actually helps
Understanding it
This sounds soft, but it’s genuinely one of the most powerful tools. When you understand that hurt doesn’t equal harm — that the pain is a sensitive alarm, not ongoing damage — the threat level drops, and that alone turns the volume down. Fear and uncertainty keep the system switched on; understanding settles it.
Hands-on treatment to create a window
Manual therapy, soft tissue work, and dry needling can reduce pain and ease the protective muscle guarding in the short term. That relief isn’t the whole fix, but it creates a calmer window in which you can move and rebuild — which is where the lasting change happens.
Graded, confident movement
The core of recovery is gradually exposing the system to movement and load it currently finds threatening, at a level it can handle, and building from there. Done right, this retrains the nervous system’s response — the alarm threshold rises, the volume comes down, and you reclaim activities one by one.
The basics that move the needle
Sleep, stress, and overall load aren’t side issues with persistent pain — they’re central. Improving sleep and managing stress directly reduce the nervous system’s sensitivity. They’re part of the treatment, not lifestyle advice tacked on the end.
The bottom line
If your pain has outlasted the injury, you’re probably not broken and nothing is necessarily being missed — your pain system has become sensitised, and that is treatable. It responds to a different approach than acute injury: calming the system, understanding what’s driving it, and rebuilding tolerance through confident graded movement, supported by hands-on treatment and the basics of sleep and stress. Persistent pain is real, and it’s also changeable — which is the most important thing to know if you’ve been told to just live with it.
