re: OT doctors, please for the love of God help me

You probably have a virus. Keep taking whatever meds to help and it will pass. Alot of it going around.

Sounds like COVID. It now a bad nasal drip. Need to shut it all down…..

Old school Sudafed. But you can’t get it without a prescription bc of the meth heads.

I have had the exact condition you are talking about. I’ve tried every medicine you mentioned plus Singulair, D-Hist, Xyzal and Chlortabs. My doctor even changed my Lisinopril BP medicine because it can cause sinus drainage but that didn’t phase the drainage.
The first several months it was not like classic post nasal drip or drainage, it felt more like having a lump the size of an M & M stuck deep in the back of my throat that constantly made me need to clear my throat. It gets considerably worse after drinking or eating anything warm or hot, also when I eat anything spicy or saucy.
But in the last 5-6 days, it has become a combination of real nasal drainage caused by weed pollen and a small lump, with some ability now to hock it up which sometimes causes your throat to feel like you ripped the skin off and left it raw.
Diphenhydramine (Benadryl) helps more than anything but it has to be taken every 3-4 hours and too much of it affects my heart rate and blood pressure. I plan to talk to my general practitioner at my fall wellness visit in a couple of weeks.
In the meantime I have to just keep irritating the hell out of anyone I’m around by constantly having to clear my throat.

That’s what shirt sleeves are for.

You've tried just about everything over the counter.

Patanase is over the counter and I think they just released azelastine over the counter as well(astepro). Those are both anti-histamine nasal sprays that may help.

Otherwise ipatropium bromide can also be useful, but prescription. Ent can always look and make sure you don't have a persistent sinusitis or other issue causing the post nasal drip if you fail the above.

Lastly, sometimes post nasal drip isn't always because of allergies/nose issues. Occasionally post nasal drip is due to reflux...so may need to consider a different treatment.

If you've had this for weeks you need to go to urgent care or a Physician. You probably have a sinus infection by now but you need to get it verified. Don't go taking antibiotics until you go the Dr.

The medical specialty here is mostly confined to STD afflictions.
Sorry.
