Complex Regional Pain Syndrome
Complex regional pain syndrome (CRPS) is a chronic pain condition that is believed to be the result of dysfunction in the central or peripheral nervous systems.
(CRPS) is characterized by pain, swelling and 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.
