Jaw pain: Follow up with doctor ,ENT and dentist ( see doctor today) . Could be TMJ or a tumor in jaw or spasm of the muscles or retropharyngeal lesion, tooth issues unbeknownst to you or it may be a heart ischemia or a reflux issue .

Tooth issues: Have you made the self-diagnosis that there are no tooth issues, or has a Dental Professional? Soreness may be from infected tooth/teeth, infected gums, broken or split teeth, clenching/grinding, malocclusion, joint dysfunction, cardiac damage, medications, and so many other causes. Please see your Dentist for examination and advice. Medical examination may also be in order.

TMJ - TMD: Temporo-mandibular disorder is the second most frequent cause of orofacial pain after dental pain. Proper diagnosis is the key for the successful treatment. See an orofacial pain practitioner for a consultation, diagnosis and management.

Get dental consult: You describe TMJ (temporal mandibular joint) syndrome features, and a skilled dentist or an oral surgeon could help you. A dental splint worn at night may reverse most if not all of your problems.
