Complex Regional Pain Syndrome

Complex Regional Pain Syndrome (CRPS) (aka Reflex Sympathetic Distrophy – RSD) is a chronic neurological syndrome that is described as a severe burning pain, pathological changes in bone and skin, excessive sweating, tissue swelling, and extreme sensitivity to touch.

There are two types of CRPS: Type 1 (RSD) is where the precise nerve injury cannot be identified; Type 2 (Causalgia) is where a very precise nerve injury has occurred. Both types have similar symptoms: skin color and skin temperature changes, continuing pain, and hyperalgesia.
