Reflex Sympathetic Dystrophy is a complicated nervous system disorder characterized by a severe burning pain that is usually localized, but may spread, and which is accompanied by abnormal changes in the bone and skin in the area, excessive sweating, tissue swelling, and an extreme sensitivity to touch.

Also referred to as Complex Regional Pain Syndrome, the disorder is classified into two types: Type I comprises cases in which there is no trauma or other circumstance, such as surgery, that can be identified as a precipitating event; Type II refers to cases in which a significant event is known to have caused nerve injury.

Generally, there is an injury to a nerve or soft tissue, from known or unknown causes, for which healing does not proceed normally and the severity of the syndrome tends not to be consistent with the apparent severity of the injury. As a result, many people suffer in silence, having been told there is nothing wrong with them or that what has happened isn’t sufficient cause for the degree of discomfort they describe.

A correct diagnosis requires medical expertise and a thorough history and physical examination. There are no laboratory tests that can document the condition, and doctors make what is referred to as a “clinical” diagnosis, based on his or her professional expertise and a thorough evaluation of the individual.

Treatment is highly individualized and may comprise medication, nerve blocks, physical therapy, psychological support, and in some cases, a sympathectomy (removal of a portion of the affected nerve), or spinal stimulation. Patients are generally monitored, even when treatment provides relief, as the symptoms are known to return with or without a separate injury. Any recurrence requires immediate medical attention.
