I also notice that when I belch I breath better. I have very bad gas.
Did you take a spirometry test? What was your result?
Thanks
Try not to think too much about it until you see your Pulmonogist. I smoked for over 35 years and quit about 9 years ago. I developed shortness of breath and after seeing the pulomonologist and doing the tests, etc, I was diagnosed with COPD. (Chronic Obstructive Pulmonary Disease) It is treatable, but the first thing they will tell you is to quit smoking. If you quit, chances are it will not progress. But you can read about it and get questions ready for your doctor. Then again, it could be related to the bathroom cleaners. Good Luck!
