Mine is just hoarseness and phlegm in my throat the keeps me up all night. My nose closes off when I lie down but the phlegm collects in my throat and makes me feel like I’m choking then I can’t breathe through my nose so I have to sit up. All night.
I found nasal spray before bed and taking guiafennessen helps but then the nasal spray stops working. The steroid one doesn’t seem to work so I used decongestant one. Then I used saline and try to get it to run down my throat a little and one side at a time move it back and forth in one nostril and blow your nose gently. After that try to hawk the phlegm out and repeat other side. Sometimes this loosens it up and you can get some out. Sleep with head elevated
In morning drink coffee this helps it go down. I’ve tried all this since I got the problem with Covid. I’ve been waiting for Dr appointment sinceNov of 2024.

Good luck! Mine doesn’t get worse with eating that seems to push awwwwit down. I’m still hoarse, I Sound like a frog.
