So, your pcp is monitoring this? If you have great insurance and it doesn't cost an arm and a leg, never hurts to get it looked at by an ENT but otherwise, it sounds like you've covered your basis. I'm glad you have no symptoms!
Hello~Even though there may not appear to be an infection anymore, it is still a good idea to have the issues causing it checked out. I would certainly see the ENT and have it taken care of. Having a hole in your tonsils and still some pus means it could flare up at any time, and this time, it could be worse.
