I had a pus pocket like that on my tonsil inside my throat. It made it so hard to live for 10 days. It poped when I was puking because my stomach hurt because I couldnt eat.

I went to the doctor a day before it burst open and after telling them how much pain i was in they said "well if it gets any worse you should go to the ER and have it looked at because it could be a cyst. If it would have burst into my bloodstream I would have died. I'm so lucky. No thanks to my shithead doctor.
