Flip,

Just saw my ENT recently with just about the same complaint. He questioned my about how much it hurt and how often. I think the issue is fairly subjective as he took my answers and concluded that i was having normal issues with the radiation traetment to the jaw. He let me know that if it got any worse or the pain sharper, I should make an appointment and come back in.

He also wanted me to keep up with my jaw exercises (I'm at three fingers)

I'm not sure if this helps.
