What Is Central Sensitization?
Central Sensitization is a nervous system process that makes the brain and spinal cord respond more strongly to pain signals. The response can continue after an injury has healed or become greater than the original tissue problem. This process may help explain widespread pain, tenderness, fatigue, and symptoms that change over time.

Key Takeaways About Central Sensitization
- Pain sensitivity may spread beyond the original injury area.
- Symptoms can change even when scans show little tissue damage.
- Central sensitization is not the same as imagining pain.
How Central Sensitization Works

Central sensitization changes how the brain and spinal cord process signals from the body. Nerves may send stronger pain messages, and ordinary touch or pressure may feel painful. The nervous system can also stay alert after the original trigger becomes less active.

Clinicians assess this pattern through the history and examination. They look at pain location, sensitivity to touch, sleep, fatigue, and how symptoms respond to activity. A scan may show a physical issue, but scan findings do not always explain the full pain experience.
Fibromyalgia often includes signs of central sensitization. Treatment planning may focus on the whole symptom pattern, not only one sore muscle or joint.

From the Premier Injury Specialists team
When we assess central sensitization, we review the pain pattern and the symptoms that occur with it. Our team considers tenderness, sleep concerns, fatigue, and daily function alongside examination findings. We use that broader view when discussing care for fibromyalgia and persistent widespread pain.
Central Sensitization in Practice: A Real-World Example
A person with fibromyalgia may feel pain across the back, arms, and legs, even when no new injury occurred. Light pressure from clothing or a gentle examination may also feel unusually painful.
