For years now I have suffered from daily, excruciating headaches that feel like crushing pressure as well as pain, mostly frontal, sometimes occipital as well. Depending on which doctor I have seen they have been diagnosed as migraines, tension headaches, and chronic daily headaches -- not helpful. Neither abortive nor long term medications have helped. The one unusual feature that noone seems to be able to explain to me (I think when I mention it they just think I am crazy) is that I can obtain some relief if I am able to "crack" my neck. Not complete relief by any means, but this consistently does seem to temporarily relieve some of the pressure. Does this provide any clue to the nature of the headache or point in any treatment direction? Thanks.
