Yesterday I had a martial arts fight, and my opponent has me very quickly, so that my neck to jerk back, I think too fast. Today when I woke up, my neck pain is worse than yesterday, and it feels like the neck muscles are tight. Even if I gargle when I do brush my teeth to hurt. I think it is a swelling on the left side in front of my neck and it hurts when I press lightly on it. Someone knows how to handle this situation?
