Could be: a rash affecting only the skin (such as an evolving contact sensitivity rash), problem with the immune system (such as vasculitis), infection or blood disorder. A physician may begin to differentiate probable causes with more information about you and the timing of the rash, as well as review photos, in a virtual consult on Health Tap.
