Central sensitization, in plain language
Why some pain outlasts its original cause — and what that means for how you describe it.

Central sensitization and chronic pain
Representative of the chronic-pain neuroscience literature
One idea that's reshaped how clinicians think about persistent pain is central sensitization: the nervous system itself can become more sensitive over time, so the volume of pain stays turned up even after an initial injury has settled.
This is not the same as "the pain is in your head." It's a real, physical change in how signals are processed. But it explains why pain can spread, linger, or seem out of proportion to any single cause — and why purely chasing one structural culprit sometimes goes nowhere.
For describing your own pain, the useful upshot is to note how it behaves over time — does it spread, does it flare with stress or poor sleep, is it widespread rather than pinpoint? Those features are part of the picture a clinician is reading.
Questions to ask your clinician
- 1.Could central sensitization be part of what's going on for me?
- 2.Does that change which kinds of treatment are worth trying?
- 3.How do sleep and stress fit into this for me specifically?
