Complex Regional Pain Syndrome Type 1 Treated with Vitamin C.

Complex regional pain syndrome, formerly reflex sympathetic dystrophy or causalgia, is a chronic progressive disease characterized by severe pain, swelling, and changes in the skin. It often affects an arm or a leg and may spread to another part of the body and is associated with dysregulation of the autonomic nervous system resulting in multiple functional loss, impairment, and disability. It occurs mostly in adolescence. Although treatment is often unsatisfactory, we report a young girl treated satisfactorily with vitamin C.
