I was brushing my teeth earlier and when I brushed my tongue and spat, I noticed a sorta milky yellow
string of what seemed like mucus
hanging behind my uvula. I tried to spit it out, but it was still hanging there. It looked like it was coming out of the top hole behind the uvula, which I'm guessing leads to the nose? Eventually, I got annoyed and tried to pull it out, but it would just slide between my fingers. Soon I figured out that I could pinch it and pull it out in pieces.
