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 that is believed to be the result of dysfunction in the central or peripheral nervous systems. CRPS is characterized by pain, swelling or stiffness in the affected hand or extremity. The pain may be out of proportion to the injury that triggered it. CRPS is usually associated with an injury, which can sometimes be as minor as a paper cut or small bruise. It causes the nervous system to misfire and send frequent or constant signals to the brain that are interpreted as painful. The nervous system becomes overactive, causing intense burning or aching pain, along with swelling and changes in skin color and moisture.
