They are small yellowish white balls that come up from the back of your throat. They smell bad, too. For the last few days I have been hacking cause I felt like there was something in the back of my throat. Tonight I look and there's 2 white balls lodged on the left side, looking disgusting. One was kind of big so I took a qtip and took the big one out. The other one was too small and the big one broke off but I got some of it. It's fucking disgusting and now I don't even want to eat. I want them out so bad but I keep gagging and even threw up a little bit. I read that If I get my tonsils removed, they will go away. I do tend to have problems with them anyway.
