Rash decision FilthyIke - 21/08/2009 20:17 - Canada Today, I went to the doctor to inquire about the rash I've been getting in my underarms, behind my knees and sometimes on my face. Turns out I'm allergic to sweat. I'm a varsity rugby coach, gym teacher, and I just shelled out a stack of cash to get a sauna and steam room installed in my house. FML 47 778 4 388
