nasonex,
afrin, mucinex-d, claritin, allegra, zyrtec,
flonase, etc. Another ENT thought it was acid reflux. I tried: prilosec for 14 days, nexium for 3 days (I had too many side effects from nexium so I discontinued it). I had no symptoms of acid reflux so I felt there was no point to take these meds, but I tried anyway with no success.
I got a CT scan and they found there was a cyst in my left maxillary sinus and mucus thickening in the ethmoid on the same side.
