I've had swollen tonsils for years (it's not tonsillitis), from time to time white puss ciss things develop on the sides. They are gross, kinda hard, crumble and smell like bad breathe. (Also I brush, floss, Listerine, peroxide a good amount). So I just realized these zit like things that develop on my tonsils seem to be deeper in my tonsils than I realized, thus why they are swollen. I never have sore throats from this either.
