I have had RSD for 11 years. In the past year I started developing cramping along with the burning pain. Recently, it has been so bad, I cry out, I cannot relieve it and it takes my breath away. Does anyone else experience this and what do you do. I have been to my GP and they did a pulse ox and ekg? Not sure what that was suppose to do. My pain doc had never heard of this??? Any help would be greatly appreciated. Thank you
