My son has had a skin rash under his armpits off and on for several months. We have taken him to his dr. 3 times. The first time they thought it was a reaction to the Strattera he had just started. This ended up not being the case. I took him back and he thought it was maybe bed bugs:(So I throughly cleaned his room and bought one of those mattress covers. In the meantime we were using hydrocortisone cream. It looks like itchy red bumps. The pharmacist suggested athletes foot cream and we have been using that several times a day and it hasn't helped at all. That has been for a week. Oh one visit he suggested flea bites. But dismissed that idea because they are usually random on the body and these are always under his armpits. Any ideas?:)
