@catt8722 Sounds as though you've done due diligence, seeing doctors and having testing but still have bothersome mucus.

What ailment did your mother have? Bronchiectasis? My last two PFTs were normal and I have had bronchiectasis and asthma for many years.

Where is the mucus coming from, your nose or chest? Can you cough anything up for a culture? How do you feel?

Bad breath makes me think of reflux, perhaps silent. There are very specialized tests to rule this in or out. Excess mucus makes me think of allergies and of course, bronchiectasis. The last is difficult to diagnose without a CT scan. Bronchiectasis is a rare disease, so they don't look for it initially. I hope for your sake it's not but this a bronchiectasis forum so we think of it!

was told to use mint listerine by infectious disease dr. and Stella Dry Mouth rinse by dentist. Who knows if it helps!
