Formerly called causalgia, the reflex sympathetic dystrophy (RSD) is a medical condition in which the patient suffers from "burning" pain, swelling, and vasomotor dysfunction in one of his arms. The exact cause of the RSD is unknown, but it could be triggered by an abnormal circuitry in nerve impulses along the median nerve branches and the stellate ganglion efferent fibers. It is also termed as complex regional pain syndrome. Treatment consists of analgesics (pain killers), stellate ganglion block (with anesthesia), and therapy.
