I am seen at the University of Texas Medical and first the dermatologist gave me a cream. It worked. Then I saw my RA doctor and she prescribed a stronger med. It stops but the very next day there will be more marks. The ones from the RA have a WHITE top like maybe puss. But I was told that is not puss, but the color of the pimple. Look it up on the pictures of Dermatology or RA. See is they look like yours. Unfortunately, the same med does not work for each person. NOT ONLY that, they told me no HOT SHOWERS. WHAT? I pretend I did not hear them. I cannot bring myself to take a cool shower.. I guess I aggrivate the rash. So mine is due to RA.
