I went to the GP a few days after posting the message above. He said the bump in the back he figured was something called "Walldire's" something or another, I can't remember the name exactly.
He prescribed me Keflex for two weeks because he thought it could be a staph infection. He said if it was an infection the bump should disappear in a week, if it's a virus then in two weeks. It's been a week and a half now and it's still there.
The bump (lymph node) on the back of my neck HAS gone back to normal and is not swollen, but my right tonsil is STILL swollen a little bit, and like I said the bump behind my uvula IS there too and looks the same.
Please, has anyone ever had similar symptoms?! I'm going to follow up with my GP if it doesn't go away by Tuesday... I'm so confused and scared right now!
