What is CRPS (Complex Regional Pain Syndrome)?
CRPS, formerly known as RSD or reflex sympathetic dystrophy, is a painful condition which usually affects an extremity. The cause of CRPS is not well understood, and there is no single test that can be used to make the diagnosis. Rather, the diagnosis is made by history and physical examination. There may or may not be a history of preceding trauma. Treatment typically consists of physical therapy and medications, with injections and pain psychology as needed.
