Complex regional pain syndrome

Common Name(s)

Complex regional pain syndrome

Complex regional pain syndrome (CRPS) is a chronic pain condition that mainly affects the arm or leg after an injury. The main feature of CRPS is continuous, intense pain that is out of proportion to the severity of the injury. The pain gets worse over time and often spreads throughout the entire affected arm or leg.  Other symptoms may include color and temperature changes of the skin over the affected area; skin sensitivity; sweating; and swelling. The underlying cause of CRPS is not known. Treatment aims to relieve pain and may include topical or oral medications; physical therapy; and/or a sympathetic nerve block.
