TMJ: Yes, all of the conditions except mildly elevated BP can cause the pain you describe. Make sure you're being managed by a TMJ-orofacial pain expert.

Headache: Neck problem and TMJ problem can cause some headache, but associated underlying causes like eye strain, stress, tension and migraine headaches should be considered and ruled out.

TMJ syndrome: Temporo-mandibular syndrome is the second most frequent cause of orofacial pain after dental pain. Headache, forehead pain, earache, sinus pain, neck pain and jaw pain are the common symptoms. Proper diagnosis is the key to successful treatment. See Orofacial Pain specialist for a consultation and treatment options.

Therapy?: I addition to consulting your GP to find out what ails you physically, have you yet tried any form of psychotherapy? Typically, the optimal combination of things to treat emotional issues such as anxiety or depression is medication (which, on your best day, is supposed to take the edge off symptoms) but the real gruntwork takes place in psychotherapist's consulting room.
