Complex Regional Pain Syndrome
Alternate Names : Causalgia, CRPS, Reflex Sympathetic Dystrophy Syndrome, RSDS, Shoulder-Hand Syndrome, Sudeck's Atrophy
Definition
Complex regional pain syndrome (CRPS) is a chronic pain syndrome with two forms. CRPS 1 currently replaces the term "reflex sympathetic dystrophy syndrome". It is a chronic nerve disorder that occurs most often in the arms or legs after a minor or major injury.
CRPS 1 is associated with severe pain; changes in the nails, bone, and skin; and an increased sensitivity to touch in the affected limb. CRPS 2 replaces the term causalgia, and results from an identified injury to the nerve.
