Re: What caused this wierd jaw problem
It does sound like it might be TMJ or a muscle spasm... I would say to try alternating warm moist heat and ice along with anti-inflamitories for a day to see if that helps.
A silly question... do you still have your wisdom teeth? It could also be an impacted wisdom tooth that has become infected... this would cause swelling and the pain might not hit for a day.
If this is not better by monday a trip to the Dr is in order, but if it gets any worse (ie- spreads to the other side or completely locks) or you develope a fever, chills or any other sign of infection I would say to head to the ER.
If all that doesn't kill you makes you stronger then just call me SuperMan
