White string at the back of my throat. It’s only on one side behind the uvula, it’s exposed and every time I swallow, it feels like a lump or when I swallow, I gag because it’s just there and I can feel it. On the other side of my throat behind the uvula, another white string is there, but it’s covered, so it doesn’t bother me. The other one isn’t covered up and I’m getting sick of this.
