Chronic Pain Definition

Chronic pain is any pain that lasts for more than three months. The pain can become progressively worse and reoccur intermittently, outlasting the usual healing process.

After injured tissue heals, pain is expected to stop once the underlying cause is treated, according to conventional ideas of pain. However, chronic pain can persist after injuries heal for no apparent biological cause.

The most common sources of chronic pain include low back pain, headache and arthritic pain. Chronic pain can cause significant psychological and emotional trauma and often limits an individual’s ability to fully function.
