DEAR READER: Reflex Sympathetic Dystrophy (RSD), today more commonly known as Complex Regional Pain Syndrome, is thought to be a chronic pain dysfunction of the central or peripheral nervous system. No single cause is known; rather, multiple causes appear to produce similar symptoms. Triggers can include infection, injury, heart disease, degenerative arthritis of the neck, stroke, thyroid disorders, shingles, specific medications and more. There is no specific blood or diagnostic test for confirmation. Treatment consists of physical therapy, exercise, medication, spinal-cord stimulation and more. Trials of Botox are even being considered for pain control.

I suggest you join a local support group or contact the RSDSA at P.O. Box 502, Milford, CT 06460; (877) 662-7727; info@RSDS.org.
