My boyfriend has rash all over his body. He says it does not itch. It feels like a windburn in a way. It kind of goes away or doesn t seem to be so bad until he starts working in or outside. Under his armpits and back of legs gets extremely bad. He has had this for a long time. He went to Dr once when he first got it and they said it was like a fungal infection. They said they would call the meds in to his pharmacy but we never did get it and don t know what it was. Its like when he gets hot or sweaty it gets worse. What could this be?ch
