I have TMJ too and sometimes get jaw pain partic on my right side as I must clench the most on that side but also seem to get more of my neck pain on that side or so it seems lately. I wear a nightguard everynight.

What you've written re injury to the face on that side and possibly your collar might be causing some pain. Have you had dental xrays recently there to r/o any dental cause for pain as well? I was watching Dr.Oz the other day and hearing that women often exhibit jaw pain and shoulder pain as part of sign of heart attack vs. classic chest pain. My Mom had angina and jaw pain was her main symptom however of course was alleviated with nitroglycerin. Still now that I'm nearing 60 (3 years from) I consider these things whereas years ago I would have just "poo-pooed" any thought like this.

Good luck w/getting it figured out. I hope it's not too painful or distracting and there will be an accurate diagnosis for the pain and treatment.
