Reflex Sympathetic Dystrophy

Abstract Reflex sympathetic dystrophy (RSD), reflex neurovascular dystrophy, and complex regional pain syndrome are all various names for the same condition. It is a cause of great frustration for parents and physicians, and it is far more common than you might think. RSD can involve the foot or hand. It rarely occurs in children under the age of eight, but may occur at any age thereafter.
