Have you found any relief yet??I caught Covid in July, and one of my symptoms was extreme amounts of thick, postnasal drip, which I am still struggling to clear! I have tried Sudafed, Mucinex, different nasal sprays (Afrin, Flonase, Saline), oral antihistamines, the netipot, and zpack(in case there was a secondary bacterial infection) but nothing has worked! I even tried Pepcid as acid reflux can sometimes cause postnasal, but that didn’t work either. I just saw an ENT doc who diagnosed me with “rhinitis,” and recommended Sinus rinses (with the bottle, not the netipot), and Azelastine nasal spray (an antihistamine spray) twice a day for three weeks to see if that helps. If that does not work, he wants to send me to an allergist for allergy testing. However, I do not think this is due to allergies as this all started w Covid!
