We are on vacation and my 13 yr old daughter started developing hives on her hands and then a day or two later on her feet and they have gotten worse even though we have been giving her Claritin, Benadryl and hydrocortisone cream. We have removed any triggers that may cause contact dermatitis and now she started getting them on her elbows and knees. I'm at a loss! We thought maybe it was hand foot and mouth but it's not. She is very itchy and now that we are far from home I'm worried as to what this may be. We are using our own bedding from home so that rules out bedbugs and no one else in the family has any similar symptoms. She isn't eating anything different, nor is she coming in contact with chemical triggers.
