My 18-year-old daughter has been sick with fatigue , bad cough, runny nose and sore throat for almost a week. Yesterday she started getting a rash around her hair and ears and it is now on her legs and arms, too. She has mild asthma so her cough is causing her to tighten up and she is using an inhaler a lot. Also she took Musinex for two days for the cough, but she stopped yesterday in case that was causing the hives . She has a pretty poor immune system and has been allergic to three antibiotics in the past. She is taking and antihistamine for the rash, but it won t go away. Help! She is in a Beauty Pageant in five days!
