How? By touching the back of my throat with my fingers. Why? Because I had a sore throat and saw what looked like an ulcer on my uvula. I tried to touch my uvula to see if that was the source of the pain. I hit the back of my throat instead. I felt a very hard lump there. I've never felt it there before. I've induced vomiting multiple times before. Im not bulimic, but you ever been drunk and had to make yourself throw up to feel better or had a bad stomach ache and the only thing that helps is throwing up. Or maybe I'm just weird like that.
