4 days ago I was at the pool with a friend. We were messing around and I had my fingers by my mouth. My mouth was open and she decided to hit my hand into my mouth. My finger nail, which was very long and sharp, hit the area of skin near my uvula. I felt extreme pain. And unnoticed later that night that it was just a small pink cut on the inside of my mouth. The next day it was white and really read around it. The pain started getting worse every day so I have been taking 3 ibuprofen every 4 hours. Every time I eat or drink something it hurts really bad. I noticed that today the cut is as bad as it has been and it's bigger and almost looks yellow and infected. Someone please help.
