Hello, My brother has a rash on his chest and underarm 4 days ago. At first it was only small,red, itchy bumps and over the last few days it has turned into *****, scabby welts. He says they hurt more than itch now. Like a blister.
He has been taking cellcept for over a year for an eye condition ( for uveitis). He also was taking care of a puppy for a friend. Could it be from one of those things?
Thanks
