Red lump/cyst on tonsil? Anyone have advice?

First I should mention that I have cryptic tonsils and have dealt with tonsil stones my entire life (and yes, my tonsils are naturally this big, for some reason they refuse to remove them). Today after lunch I discovered that I had this red, hard lump inching out of my tonsil. I'm not sure what it is. It only hurt whenever I touched it/prodded it a few times. I will call the GP tomorrow and hopefully get something figured out but I'm wondering if anyone has dealt with this before. I'm trying not to worry.
