I had my physical yesterday and my doc is sending me for a pulmonary function test at the hospital tuesday. Has anyone had a PFT? I'm just wondering what to except. My doc gave me an inhaler already, Proair, for when I wheeze or get short of breath. I've had to use it once already and noticed a difference after I used it. Surprised the h*** out of me that it actually did something. I've been in denial that I could have asthma for a few years now. Any info would help me.
