Hi I did not have an injury either but have RSD and PN. It is very important though to rule out other conditions. I have had multiple mri,emgs,xrays I mean I could go on. Can you see a pain specialist/anestesolgist? What state do you live in? Maybe someone could suggest a pain doc who deals with RSD. If not I would call a major hospital or teaching hospital in your area there pain clinic and explain you have rsd and want to see if they have a pain specialist who deals with that. Have you had any blocks? Are you on any meds?
