I got that too and it was because I had, had soo many tonsil infections in the past that my tonsils were scarred and it was trapping food and pollen in them, when I took one to my dr he said oh well lets go ahead and schedule you with the Ear nose and throat specialist and they took my tonsils out!! I know that those tonsil balls (thats what my mom and I called them lol) are annoying and super gross!! They also seemed to come around the time I was getting sick again!! Hope I was at least a little helpful my dr never did give me a name for them!!!
