my cousin used to get asthma attacks
when she was a young girl, she took
a series of this shots, and now she is totally free from asthma.

That’s tough. I don’t really know what to do. I have exercise-induced asthma too. Maybe you can try warming up more before you start the heavy running? Make sure you take your inhaler before practice if you doctor prescribed you to and be careful.

So hopefully things get better man, and I think people will understand that you have asthma and have to take precautions.
