I have had this white cyst looking thing on my tonsil for years. I had showed it to my dentist when I first noticed it and he said it was food getting stuck in there (yuck) but nothing to worry about. Since then it has doubled in size, but really causes no pain or symptoms other than occasional sore throat. From my research on the Internet, I think it could be a tonsil stone. But I've read tonsil stones can come and go and this just stays there. I have never coughed up any tonsil stones either. Anybody had anything similar or know more about this? I have a dr. appt., but thought somebody could ease my mind while I'm waiting.
