Pocket of white stuff above my tonsil? Nurse or doc , med student, any opinion PICTURE!!?

Actually cysts normally cause pain,swelling, etc. It's most likely just a tonsil stone. If you look at your tonsils you will see that they are wrinkly with small ridges all over. A tonsil stone is when a small piece of food gets caught in one of those wrinkles and your body fights it by covering it with a mucus, like a pearl. They often cause bad breath and taste worse, but they fall out eventually, and sometimes have to be removed by a doctor. I didn't look at your picture because I am a bit squeamish, but if you are having no discomfort then if is probably just a tonsil stone. If you are very scared, you should go have your doctor look at it just to be sure.
