Do I have asthma???????

[HannahMcEwen]

Hi! I have always been very fit and active. But nowadays, I will run around our school track in gym and be wheezing and having trouble with things that are easy for my legs to handle, but not my breathing. My friends think that I have asthma. Even my friends with asthma tell me they think I have it. How do I tell my parents about this?????
Also, what are some of the symptoms of asthma? I know abotu heavy breathing, but anything else?
Thank you!
Hannah
