Last night he had an allergic reaction (hives and itchy skin) to mosquito repellant. We think it was the citric acid in it. We treated it with Benadryl and cortisone. Tonight he can t sleep. Says the bottoms of his feet are itchy. I do not see anything fungal going on. HIs feet are red...but that s probably from rubbing on the carpet to get rid of the itch. I think it s partly in his head. Any ideas?
