Hi! I am looking for information. I am curious about the part small airways play in asthma. For the last few days I have been feeling rough, as if I am getting a proper head cold, but without getting one. Not yet anyway. Anyway, my breathing has felt affected, it feels heavier, and a little extra coughing, (the other night it wouldn't stop, so I used the ventolin and sucked on a strepsil. One or the other worked.) So nothing much to make a fuss about, but enough for me to notice. However, my peakflow so far as behaving normally. So, I am wondering if this could be small airways being more inflamed? Any learning out there would be most welcome. And any references anyone might have.
