RSD is a result of a nerve disorder affecting specialized nerves that supply the sweat glands and blood vessels of the skin. Under certain conditions, these nerves take over abnormal functions and start shooting off abnormal pain impulses, resulting in tissue changes. If these conditions are diagnosed early, the chances of cure and prognosis are excellent. However, if they are misdiagnosed, and are prolonged, then there will be irreversible damage to the tissues and the chances of cure and prognosis are poor. In your case, if you’re proven to have RSD, then certain procedures that target the sympathetic nerve tracts will need to be performed. These maybe specific nerve blockades of the sympathetic tracts or ultimately a radiofrequency ablation which permanently destroys the troublesome nerve. This is usually combined with physical therapy to restore function.
