i have had asthma sense i was little. i am 14 years old and just started high school basketball a month ago. during practice and games it is hard to breathe and it affects how much i can run. just the other day i was sick with a cough and i went to practice, it was hard to breathe, my chest hurt, and i felt nauseous. and whenever i have to take a deep breath i have to lean over, put my hands on my legs and push up to get a full breath, but sometimes i can only feel the air going into my right lung. and after i run a lot, i will breath quickly and heavily. when i do that, i feel something in the back of my throat vibrate, making it even harder to breath. and ever sense practice started my asthma has been affecting my when i am just sitting around at home. (i am taking 2 puffs of flovent twice a day and i use my inhaler when needed but it isn't helping) why is this happening?
