Mysterious shortness of breath: What has helped you?

My SOB started about 4 months ago, 2 weeks after my second COVID vaccine shot. But it happens only after playing tennis continuously for 30 to 90 minutes. The X-rays image showed possible paralyzed diaphragm (elevated right side diaphragm) but sniff test and CT scan were normal so my doctors are ordering more tests (pulmonary functions test, echocardiogram, calcium score test). While waiting for further tests to find out, my SOB is mysterious to me at this moment. However the difference between my mysterious SOB and yours is that my problem only appears after 30-60 minutes of vigorous exercises.

@kevintran- Have you thought about Exercise-induced asthma? I have it and nothing on my lung tests suggests that I have asthma.

I was just about to make the same suggestions as Merry. Both of my daughters suffered from it during high school athletics. One even got a "trophy" her junior year (5th year competitive skiing) for "First Race without an Asthma Attack." I always got it from exertion in high heat/humidity and it wasn't diagnosed - until it developed in my 40's into full-blown asthma.
Another possible cause is known as "reactive airway disease" which occurs when airways are irritated by pollution, pollen, exertion or another trigger, causing wheezing or shortness of breath, but asthma is not yet diagnosed. It is often treated with the same meds as asthma. When I was a kid it was sometimes called "bronchspasm" by the pediatrician.
The definitive test is exertion until it occurs, and then checking your lungs and airways.
Has anyone suggested this as a cause?
