I have TMJD and experience all the symptoms you describe. The only thing that helps me is to have my husband massage my neck and shoulders, as the headache I get from clenching my teeth can be very painful. The trigeminal nerve is very long and travels through all parts of the face, jaw, teeth, ears and when you have TMJD it gets irritated very easily.
Many of us have had expensive mouth guards made...I am one of them, but it gave me canker sores so I don't wear it.
