I’ve had constant mucus in throat since Covid 3 years ago.

I, too, have had lingering sinus problems since having Covid. I get some relief by taking Tylenol Nighttime at bedtime. The antihistamine in it reduces the constant drip that can cause coughing that disturb sleep, and the acetaminophen helps with my arthritis. (Costco’s Acetaminophen PM is cheaper and just as good.) Every morning I use Flonase, for which I followed the directions in the package insert very carefully: two sprays for a week, then one spray daily. A warm mask or compress can also help. As others have mentioned, hydrate, hydrate, hydrate. A humidifier in the winter and an air purifier year round are also helpful.

I tried that Flonase stuff and it did not make any difference either. There's got to be an answer out there somewhere...

I took have mucus in throat and a lot of saliva in mouth. It is embarrassing when drooling. Isn't there something to combat this?
No one seems to know what to do.
Any ideas appreciated.

@bluesmanbill saw your post, and there are a few like it on Mayo…

Your symptoms very closely match mine…. I have had issues since I got sick in early March 2020, before we even really knew what covid was - but I have had confirmed infections in August 2023 and February 2025.

I am still suffering a lot of nasal and GI issues - did you ever find any help for yours?

Thanks!

@oly78 Sadly no. I've tried a number of different things and nothing seems to work--I've had good days and bad with regards to the symptoms and I have no clue as to why. The ear, nose, and throat specialist I've consulted with told me that he can't offer any solutions to my issues and that I will just have to learn to live with them. I wondered if my medication may have affected me but it really all began before I was on any meds. It's been well over 8 years when it began and only worsened since. I know that my saliva is sticker than it used to be and something altered that--I've tried changing my diet by eliminating certain foods etc. but none of that made any significant difference. It seems to first occur after I eat breakfast and usually by the evening it's improved. Sorry that I can't offer any advice or solution--I certainly wish that I could! Hope you find one--good luck.

@rosie100 have you considered that it might be silent reflux? It can very much cause this without having the typical reflux symptoms. Mucous in the throat & thickened saliva are both symptoms.
