Not sick, wheezing lung off and on thru day bad cough when it happens bending over makes it happen sometimes xray looked good bronchitis 3 weeks ago?

Reflux. When you hear your own wheezing, it is usually coming from the larynx, which can get irritated by reflux. You do not have to feel heartburn, and it can even chemically irritate your lungs, bronchitis etc. More common.
