Sympathetic Nerve Block Procedure
The sympathetic nervous system is a collection of nerves that control multiple functions throughout the body. It originates from the spinal cord and generally helps control temperature, blood flow and sensitivity. In addition, branches of those nerves combined with other nerves form the spinal cord that play a role in pain perception and transmission (sympathetically mediated pain). The most classic entity associated with the sympathetic nervous system is the pain from RSD (reflex sympathetic dystrophy). The most current state is known as complex regional pain syndrome. The pain is usually described as a burning in quality and usually involving the distal portions of the extremities (arms, hands, legs, knees, ankles or feet). However other pain descriptions such as deep, aching, throbbing or stabbing pain are common. Pain with light touch or pain with exposure to cool temperatures that are usually not painful may occur.
