I get them. I've gotten some huge ones. I get them mostly when I'm sick, and I think my sister said something about they have T cells or white blood cells in them or something. I can't remember, so don't quote me on that.
They suck, but I will just stick a finger in my throat and pry them until they come out. It hurts and usually hurts my tonsils as well, but once they're out they feel so much better. Sometimes they work out on their own, it usually when I'm sick with a bad cold that I get the big ones I have to work out on my own. And yeah, they're disgusting. Don't smell them, ever. I was curious, once. lol.
As far as I know, the only cure is removal of the tonsils. I hadn't heard they could also be caused by allergies, but I don't have allergies, so that may be why I only get them when I'm sick.
