Central sensitisation: why pain persists long after tissues have healed
Pain that doesn’t fit a clear pattern — or has lasted longer than expected?
The myBackPain assessment identifies features consistent with central sensitisation and guides management toward the approaches with the best evidence. Results in minutes.
What is central sensitisation?
It is a normal human response to be concerned when something hurts. When you don’t understand why, it can be doubly concerning and puzzling. Central sensitisation describes a state in which the central nervous system — the brain and spinal cord — seems to amplify pain signals unnecessarily. You could compare it to the princess and the pea analogy. It is one of the most important concepts in modern pain science and helps explain why back pain can persist long after any original tissue injury has healed, and why some people experience more pain than others with apparently similar conditions.
In many ways, how we respond to discomfort and pain is unique to each individual and is to an extent a reflection of each of our unique personalities.
Pain is not simply a signal from damaged tissue. It is the brain’s interpretation of threat — a protective output designed to make you take action. Normally, when tissue heals, the pain reduces and resolves. In central sensitisation, the nervous system remains in a heightened state even after tissue healing, continuing to generate pain signals that are out of proportion to the actual tissue state.
This is the most important thing to understand. Central sensitisation means the nervous system is genuinely producing pain — but the driver is in the system itself rather than in the tissues. This distinction matters enormously because it changes treatment. Treating the tissues (injections, surgery) has limited effect. Treating the nervous system — through exercise, sleep, stress management, education, and graduated activity — does.
Signs that central sensitisation may be involved
- Pain that is widespread and does not follow a clear anatomical pattern
- Pain that persists long after the expected healing time
- Heightened sensitivity to touch, pressure, temperature, or noise
- Pain significantly worsened by stress, poor sleep, or low mood
- Multiple co-occurring pain conditions (headache, IBS, widespread aching)
- Imaging that does not explain the degree of pain experienced
- Pain that varies significantly with psychological state — much better on holiday, much worse under stress
What helps?
Pain neuroscience education
Understanding the mechanism of central sensitisation is itself therapeutic. Research shows that patients who understand why pain persists experience less fear, less catastrophising, and better outcomes. Knowledge is genuinely analgesic in this context.
Graded exposure to activity
Gradually increasing activity and loading, despite pain, to retrain the nervous system that movement is safe. The pain may initially increase before it improves — this is expected and does not indicate harm.
Sleep
Improving sleep quality is one of the most powerful interventions for central sensitisation. Poor sleep directly amplifies pain sensitivity through multiple mechanisms. Sleep must be addressed as part of pain management, not as a side issue.
Stress management and exercise
Chronic stress amplifies central sensitisation. Mindfulness, CBT, ACT, and regular aerobic exercise all address this. Exercise is one of the most evidence-based treatments for central sensitisation and produces measurable changes in pain processing.
Social connection
Social isolation amplifies pain perception. Maintaining relationships and social engagement is genuinely therapeutic — not a luxury or a distraction from managing pain, but a clinically meaningful part of recovery.
