Complex Regional Pain Syndrome (CRPS)
What Is It?
Complex Regional Pain Syndrome (CRPS) is a painful and long-lasting condition. CRPS usually causes severe, constant, burning pain in the affected arm or leg.
The cause of CRPS remains unknown. However, this condition can be triggered by damage to nerve fibers in tissue that has been injured.
Experts believe that in CRPS, nerves become overly sensitive. Painful signals become more painful. And common stimuli, such as light touch and temperature changes, also are experienced as pain.
