Hi I stopped smoking almost 2 years ago. For the last year I have had a build up of phlegm, runny or blocked nose and can sneeze quite often without having the cold. The worst part is the wheeze which is particularly bad when I exercise or laugh and is prominent through the night. I have a phlegmy cough with it. When I over exert myself at an exercise class, I feel as if my tubes are closing in on me and can't breathe. It seemed to settle during the spring and summer when I was taking antihistamines for my hayfever, but now is back with a vengeance. Does this sound like asthma or something else. I'm a 33 year old female
