Complex Regional Pain Syndrome
Summary:
Also called Complex Regional Pain Syndrome (CRPS) and Reflex Sympathetic Dystrophy Syndrome (RSD), RSD/CRPS may affect virtually any part of the body and many body systems. It is thought to arise from a nerve or tissue injury, often on a limb, which for some reason fails to follow the normal healing path. After the injury (which may be slight) has healed, the nerves in the area behave abnormally, causing pain.
Although RSD/CRPS is difficult to diagnose, if unrecognized and untreated, the problem can spread to other areas of the body resulting in permanent deformity and chronic pain. Physical therapy and sympathetic nerve blocks ease the condition if begun early enough.
