I've had this feeling that something is stuck at the back of my throat for a couple of day. Just had a look in the mirror and it looks like the uvula (thing that dangles in middle of throat) keeps touching my tongue, especially when I lie down, and I get this chocking sensation. I had covid a couple of weeks ago so don't know if it's anything to do with that. I'm scared to go to sleep in case I choke. Please reassure me, I have awful health anxiety
