i'm 27 years old. i quit smoking cigarettes 3 months ago. within a couple days after quitting, i got very sick for about a week and coughed up a lot of phlegm and snot. my right tonsil started to swell during this cold as well. after about a week of being sick, everything went away but not the swelling. i continued to watch this swelling in my tonsil for the past couple months, it aches every once and a while, and i get some pressure in my right ear that can be very annoying sometimes. 2 days ago, i noticed a lot of white (puss?) stuff on my right tonsil inside my mouth. it's really annoying to swallow or talk or do anything really. is this possibly tonsil stones? how can i be sure?
