I had a game today, and i was on defense, there was a couple girls shorter than me, and was standing in front of me. She was fighting for the ball with my team mate, and he shoulder came up under my chin, knocked it. I heard my jaw crack a bunch right when that happened.
After, i could barely talk, i can still barely talk it hurts, i cant really chew. And it hurts to open my mouth or close it. My coach felt it and said it was swollen. I also have TMJ (Jaw locking syndrom) if that makes a difference.
