i get rashes and sores all the time all over my body from rsd. the latest is a rash on my scalp that i have had for over two years now. as it spreads it makes me lose patches of hair which eventually grow back and then i lose patches somewhere else. rsd symptoms are very weird, but my pm dr told me that he knows of someone else who has the same thing and that there is not much to do for it except wait it out. i was given a cream to help with the itching and burning sores but its not helping too much. just have to wait it out. hope your rash goes away soon. some of mine do like on my back, neck and ears and even in my mouth, but then they come back again at a later time. soft hugs my friend.
