Complex Regional Pain Syndrome - CRPS
Formerly Known as Reflex Sympathetic Dystrophy (RSD)
Complex regional pain syndrome (CRPS) is a pain condition that is constant over a long period of time. It is believed to be the result of dysfunction in the central or peripheral nervous systems. It causes the nervous system to send frequent or constant pain signals to the brain. The nervous system becomes overactive, causing intense burning or aching pain, swelling, changes in skin color and moisture.
