Central Sensitization: Implications for the Diagnosis and Treatment of Pain

DISC COMMENTARY
This foundational paper explains central sensitization, a state in which the central nervous system becomes hyperexcitable and begins amplifying pain signals, even without ongoing tissue damage. It set out concepts that remain central to how modern pain science understands chronic pain.
What was studied?
Woolf reviews the physiological evidence for central sensitization, describing how the nervous system can change, distort or amplify pain signals independently of the original site of injury, affecting intensity, duration and how widely pain spreads.
What did they find?
Patients affected can experience hyperalgesia, where normally painful things hurt more than expected, and allodynia, where things that should not hurt at all, such as light touch, become painful. The nervous system becomes globally more sensitive to sensory input.
Why it matters
This gives a scientifically established explanation for why some pain feels far more intense or widespread than the original injury would suggest. It reflects genuine nervous system changes, not an exaggerated response.
Why we included it
It demonstrates why pain intensity alone cannot be read as a direct measure of tissue damage, a principle that shapes how presentations are assessed.
