I have been told that you don't have to have all the symptoms to have rsd. My rsd spread has come without skin changes but the pain is super high that is for sure and I have been tested for everything under the sun that could it be otherwise. I will say though that I have had some other pain conditions through this that I have thought may have been rsd but were not and did pass but it took so long. I seem to heal slower then molasses. Anyhow I hope you can get into the doctor asap to get more direction on what is happening with you. Till then I know how hard it is but it may not be a spread so try to stay in the moment I guess that it was I say to myself. Easier said then done I do know. Many better wishes
