Yesterday morning I was in one of my classes and we were reading a play. I was in the middle of a yawn when it was my turn to begin reading. I was still yawning when I began to talk and I heard and felt a crack by my right ear in my jaw. It hurt incredibly bad in the instant it happened and has not stopped hurting within the past 24 hours. I can barely eat anything and my right ear has been causing me pain as well. When I yawn it feels fine until I go to close my mouth, than it hurts terribly bad. I was going to give it a few days before I saw a doctor about it. I was just wondering if you had any idea on what the problem could be?
