About a month ago, I subbed for a teacher in a room that smelled ridden with mold. I was there only an hour. four or five days later I had tightness in my chest and lower throat area. It is still there. I had zithromax at home (refill) and I used it thinking I had a bronchial infect. 4 days after the 5 pack I got an itchy,red,sunburned feeling rash all over my neck for about a day. It went away, and then later that week my airways swelled and it was hard to swallow food. At night it is worse and the dr. gave me an albuterol,nasonex, and allergy med. I have only had small bouts of hayfever ever in my life and am very healthy. Never asthma. He said it is allergy induced. When I use the inhaler, 10 min. later I feel bad again, it doesn't work. I can breathe but my chest still hurts. No fever, no more rash. I am 40. What do I do?
