About a week ago, I started having problems breathing. On the first day, I kept feeling I wasnt getting enough air but if I were to breathe harder, I actually get dizzy. Then my chest started feeling tight and heavy as if something was squeezing it. This lasted about a day. The following day I was feeling fine. Then the next day (Thursday) the tight chest feeling came back mid day till the night. On Friday I felt fine again, just that I ran out of breath fairly easily. On Saturday I was fine until I went to the gym. Didnt do any cardio exercies or anything, just weights. I started getting that tight chest feeling, although not as bad.
I dont smoke, although I do get second hand smoke some times. I never had asthma, and I dont have any allergies that I'm aware of. Can anyone help me figure out what might be my problem?
