No one knows what causes Reflex Sympathetic Dystrophy Syndrome (RSDS), also known as Complex Regional Pain Syndrome (CRPS), or why it follows an estimated 5 percent of all injuries. It's an under-diagnosed and under-treated neurological syndrome characterized by swelling, skin discoloration, stiffness, and intense and chronic burning pain. RSDS affects as many millions - most often set off by a relatively minor physical trauma, but can also follow surgery or more serious injury. The diagnosis is often missed in the early stages of the disease, and when left untreated the syndrome leaves the sufferer bedridden and in incredible pain. Peter Moskovitz, M.D., and Linda Lang offer for the first time to the lay reader an in-depth explanation of RSDS, the most current and effective treatments, and numerous self-help strategies for dealing with the syndrome's painful symptoms and psychological affects. From their work as Board of Directors for the RSDSA - the leading patient advocate and research foundation in the United States for RSDS patients - Moskovitz and Lang are able to help readers make sense of this complex syndrome, get appropriate medical care, manage their pain, and regain control over their lives.
