I don't have this but do have a skin condition but it is not just on my rsd. I have read of others though who have rashes etc. Do you take as needed meds when you get stressed in a flare that could be causing this possibly? I wish I had answers for you. I do have a seperate condition but it all over that I got after my rsd and had to go to a dermatolgist. Are you seeing a pain doctor too who deals with rsd? I would because I know the ones I have worked with are more aware then the neuro with other things like skin changes etc with this.
