I have asthma, regular and exercise induced. I feel your pain. Whenever I start to run or play a sport, if I don't take my inhaler like ever 10 minutes, I can not breathe at all. If you don't have asthma, lucky you as it is hard to describe the sensation that I get. Picture a 300 pound weight on your chest that gives you a hard time breathing and that's the closest that you can get to the asthma feeling. What is happening inside of me is that when I exercise, my lungs shrink a bit and get tighter, making it harder to breathe. Asthma attacks are the worst, too. You suddenly can't breathe, and even your inhaler can't help. You need to go to the hospital and get medicine through a giant inhaler type machine. [/Long Description of Asthma]
