Complex Regional Pain Syndrome
Complex Regional Pain Syndrome (CRPS) is a chronic condition, also known as reflex sympathetic dystrophy. Symptoms include an unexplained feeling of pain and discomfort that most commonly affects an arm, leg, hand or foot usually after an injury. Often, it begins in the hand or foot and then spreads to affect the entire limb. CRPS is also characterized by changes in skin color, temperature, and/or swelling in the affected area. It is believed to be caused by damage to, or malfunction of, the peripheral and central nervous systems. The central nervous system is composed of the brain and spinal cord; the peripheral nervous system involves nerve signaling from the brain and spinal cord to the rest of the body.
