Hi, i'm 19years old college student. I ran a mile today. I haven't ran in a few months but i do spinning and aerobic classes from time to time so i am not completely out of shape. But after about a half a mile my chest felt extremely tight and my lungs were burning, a point where it became painful. It became harder for me to breathe as i kept running. My chest was on fire when i stopped, i have bad sinuses so i was coughing up alot of mucus. I also had a slight pain in my back for about 20 minutes. I walked for about 20 minutes untill my heart-rate slowed down. The pain went away but now I am wheezing when i beathe in deeply, or breathe out deeply, or when i cough or laugh. I still feel a little  tension and discomfort in the center  and outer parts of my chest. I am worried there is something wrong, i have never wheezed while i breathe. It's been about 15 hours since i went running & i am still wheezing. I am not sick and do not smoke. Do i have Adult Asthma? I forgot to mention i always breathe through my mouth and not my nose when i run because i can't get enough air if i breathe in my nose, i'm sure it's due to my inflamed sinuses, but could that be the reason of my wheezing?

help!
