Hi all. I have been diagnosed with a few allergies. I'm having some problems with breathing. I sometimes cough and have chest pressure. I have had several tests and all have come back normal. My problem is that I still have breathing problems. I was told that I may have a little asthma but when the meds that they put me on did not work they simply took me off them and that was that. The meds were two puffers. One was purple and the other was blue.Is there other meds for asthma?
