Reflex Sympathetic Dystrophy Syndrome

It is possible that the main title of the report Reflex Sympathetic Dystrophy Syndrome is not the name you expected.
Reflex sympathetic dystrophy syndrome (RSDS), also known as complex regional pain syndrome, is a rare disorder of the sympathetic nervous system that is characterized by chronic, severe pain. The sympathetic nervous system is that part of the autonomic nervous system that regulates involuntary functions of the body such as increasing heart rate, constricting blood vessels, and increasing blood pressure. Excessive or abnormal responses of portions of the sympathetic nervous system are thought to be responsible for the pain associated with reflex sympathetic dystrophy syndrome.
The symptoms of reflex sympathetic dystrophy syndrome typically begin with burning pain, especially in an arm, finger(s), palm of the hand(s), and/or shoulder(s). In some individuals, RSDS may occur in one or both legs or it may be localized to one knee or hip. Frequently, RSDS may be misdiagnosed as a painful nerve injury. The skin over the affected area(s) may become swollen (edema) and inflamed. Affected skin may be extremely sensitive to touch and to hot or cold temperatures (cutaneous hypersensitivity). The affected limb(s) may perspire excessively and be warm to the touch (vasomotor instability). The exact cause of RSDS is not fully understood, although it may be associated with injury to the nerves, trauma, surgery, atherosclerotic cardiovascular disease, infection, or radiation therapy.
