Small blisters, almost too small to see, would form on the upper edge of my upper lip, and in the corners. They would burst after a day or two, then the skin
would peel off
to lots of pain and itching. Then more blisters, peeling, etc. Repeat cycle every 2 days or so. The blisters spread to my lower lip. I was prescribed strong antihistamines, anti-fungal creams in increasing strengths, and Valtrex - none of which had the slightest effect.
