I was diagnosed with exercise-induced asthma (based on symptoms) by a couple of different PCPs. A number of years later, a pulmonologist did extensive testing with some funky and fascinating equipment and determined I don't, in fact, have asthma and all the asthma meds the docs were giving me were useless.
I have had Cpn and other pneumonias multiple times, which may have complicated the picture. The only thing that seems to keep my pulmonary symptoms under control is a lowish dose (2 tabs daily) of Equilibrant, so it appears my "asthma" is actually pathogen-related.
My daughter was also diagnosed with exercise-induced asthma, but has not had the more sophisticated testing. She, too, has not had asthma symptoms since she's been taking immune modulators including Equilibrant.
