CRPS OVERVIEW / DESCRIPTION. Complex Regional Pain Syndrome, CRPS, formerly known as RSD Reflex Sympathetic Dystrophy, is a progressive disease of the Autonomic Nervous System, and more specifically, the Sympathetic Nervous System. The pain is characterized as constant, extremely intense, and out of proportion to the original injury.
Knowledge center. Complex regional pain syndrome, also known as CRPS is a rare, chronic (long-term) and progressive condition characterized by severe pain, inflammation and changes in the skin. Patients commonly describe the pain as a burning sensation, which affects one of the arms, legs, hands or feet. CRPS used to be known as reflex sympathetic dystrophy-however, when possible causes of CRPS were later discovered, the name was changed. Experts are not sure what the cause of CRPS is. We know that injury or surgery may have occurred before the onset of symptoms.
