For heavens sake, it sounds like you are allergic to sulfa drugs like me. Can you take benadryl? If I were you I would STOP the drug, take some benadryl (I was told 2 every 6 hours) and get in to see your Dr.! Bad allergic reactions can put you in anaphalactic shock you know. When I took the sulfa med I threw up and had a rash all over the insides of my ears itched, between my fingers and toes and another place I can't mention in a post! Ended up in hospital, almost died. Not all people are allergic, but those of us who are, it is a real problem.
