This week’s case is a 22 year old male who reports recurrent and intermittent episodes of rashes. He describes them as intensely itchy patches on his chest and arms, and states he has experienced them for the past 10 years. Whenever the episodes occur, the rash remains for about a half an hour and then as suddenly as it occurs, it resolves. The most recent episodes he can recall include following bathing, and after walking outside on a rainy day.
He wonders, could I be allergic to water?
