I've had asthma for well over 20 years (I'm 31) and I feel as if my problems are stemmed from the new inhaler. I've taken albuterol, advair, singular all fine with no problems. A couple of months ago I tried the new inhaler and thought nothing of it but the bad taste. About a month later I noticed a white patch/bump on the roof of my mouth where the hard palate meets the soft. Went to an ENT, biopsied it, and it came back negative; they wrote it off as just an abnomality. Well I went back to my old inhaler and I noticed that the bump was still there but hardly noticeable. I am now on the new inhaler again and the bump is back full force. I also have been getting headaches and sinus pressure headaches around my eyes & nose. I've never had this before. I wonder if there is something we can do to fight for the old version to remain on the market. Anybody else have anything similar??
