There is as well, edema, changes in the color of the skin, trophic changes, and dystonia. The pain syndrome is often triggered by minor trauma. ⋯ It is assumed that the function of the NMDA receptor has changed in the central nervous system and treatment with intravenous ketamine, is an option. Spinal cord stimulation of the dorsal horns of the spine has been effective as well. In majority of cases the syndrome resolves in the first two years, but for the rest the prognosis is dire, symptoms getting worse and persisting for years and even decades.
