My older son was in high school when his started out of the blue. He was having problems breathing and feeling weak during track season. He was diagnosed with exercise induced asthma and also has some allergies. He managed very well with a maintenance allergy medication, nasal spray, and a maintenance inhaler. He was on all of these for a while all the time, but then sort of outgrew a lot of it so that he only did the regimen during cross country and track season. He always had a rescue inhaler as well, but rarely needed to use it. He just finished up college and ran all four years as an elite athlete in division 1. He does not have nearly as many issues as he did before and usually does not have issues with running now, but can run into problems if he has a head or chest cold.
