Reflex Sympathetic Dystrophy – More recently know as CRPS or complex regional pain syndrome, this is a natural reflex of the body that is only present due to some other stimulus. It is frequently treated by blocking the sympathetic nervous system with a local anesthetic injection for temporary pain relief. The goal is to block the nerve repeatedly so that it reduces its intensity and stop reflexively returning to its hyperactive painful state. A more appropriate approach is to identify the underlying stimulus for the sympathetic hyperactivity so that both the underlying cause as well as the sympathetic reflex can be resolved and the body can be given the opportunity to heal.
