My asthma is definitely allergy-related. I saw my allergist today, and he did a spirometer test (that tests your lung's capacity for air, or something to that effect), and it was a lot worse than the one he did a month ago. Not to mention, I was pretty much hacking up my lungs when I was in his office. He switched me from Advair to Symbicort, and he switched the Veramyst, too, to some other kind..Nasocort? (Can't remember the exact name). He also gave me a prednisone shot to help me breathe until the new meds kick in, and it's really helped. I start allergy shots on Monday, which they've told me will drastically help my asthma. So, in my case, the asthma IS due to the allergies.
