Yes I had tonsil stones post Gamma Knife. They came about a month apart for about a year, I am 3 years post GK and can't remember when my last tonsil stone happened. Not painful gave me a raspy throat trying to hack a hair ball to get rid of them but generally just a nuisance. The definition of a tonsil stone says it's probably food debris lodged in the tonsil. Prior to diagnosis there was a period of time that I would get tongue tide while speaking and frequently bit my tongue chewing gum. I didn't have any problems with my facial nerve, mouth or tongue post op. I also have a swollen lymph node in my neck below the ear AN side, coincidentally the same side the tonsil stones occurred. I had the swollen lymph node prior to diagnosis with AN by 2 years. My Dr's are not concerned with either, they say only worry if the lymph node gets hard, as long as it is soft and squishy it is doing it's job. And none of the 3 are connected. Who knows.
