I have allergies as well, have been told my post nasal “drip” (actually thick yellow mucus) is from acid reflux, and am also post sinus surgery. I’ve been on antibiotics about 25 times since my sinus surgery 3 years ago. Each time all my symptoms (all are sinus related) go away for a period of time (including the thick mucus down the back of my throat and daily fevers). I’ll add that the past year I take antifungals with my antibiotics and have seen even more dramatic improvement when that happens.

And like you, PPIs do zero to help my sinus situation. I had an endoscopy this year to check for signs of reflux and have none.

During the past 3 years I worked with a diagnostician to try to figure out what’s going on, and though the problem still exists, yet luckily gets less intense each year, we found out I have cyst fibrosis. I was diagnosed with it last year, through genetic testing, at age 58. Do you have a history of bronchitis and or sinusitis? I’m asking because CF can cause thick sticky mucus. My CT scans at this point always show mucus and inflammation in my sinuses, and the radiologists always report pan-sinusitis, but ENTs always tell me it all looks great in there.

I have not found an ENT that wants to explore any issues except those for which they can do surgery. They don’t seem interested in finding the pathology for a sick nose if a CT scan doesn’t show a deformity/polyp/fungal ball — in other words, something they can do surgery on.

I recently went to a new dentist who found a small pocket of infection on an X-ray of my front tooth that had a root canal. I just got that fixed and am feeling prey good, but I’m also on day 12 of my current course of Augmentin and Itraconazole. Time will tell if that tooth issue was contributing to my issues.

I hope you find some answers.
