I'm sorry to hear you got hit. It probably knocked your bite off and your body has been compensating until now (posture/stress?). Your symptoms do point to traumatic TMJ. If I were you, I would find a dentist as soon as possible who dedicates much of their practice to TMJ. You also might think about physical therapy.
If you are having problems to the point you can't function right now, you should ask your family doctor (or the dentist) for a muscle relaxant like Zanaflex, or Valium or Zanax for a few weeks to see if you can't get the muscles to relax enough to function. Treat your jaw like it is sprained. Rest it by eating only softer foods for now. Rotate using ice and moist heat.
These are just a few suggestions, but I would really get to the dentist as soon as you can. I pray that you will find the help you need.
God bless...
Carol
