3 years ago, I met a man and we engaged in sexual activities. I proceeded to perform oral, and it was particularly violent. In the middle of the act, my jaw locked and won't budge. After a couple days, my jaw was still having problems, and I went to the doctor. He prescribed me a muscle relaxer and said I pulled a muscle in my jaw. To this day, I cannot open my mouth wide enough to comfortably perform oral on my mate. I cannot eat anything besides soup, without experiencing jaw pain. I wake up, and in the morning, my jaw is incredibly sore. I can't believe a pulled muscle can last 3 years. What else could be causing this? Please help. Thanks!
