text: You seem to have a combination of unassociated problems. Having TMJ (Tempo Mandibular Joint Syndrome) may be part of the problem (grinding your teeth) \n\nIf you are getting poor sleep (cause you are grinding your teeth and also because you are in pain from the headache)) it can raise your blood pressure as well.\n\nTachycardia arythemia (sp) is the irregular heartbeats where it races and then slows. I am not sure what would cause this in relation to the other mentioned problems. However, I would strongly advise you to see a physician who can narrow down some of the causes of your issues. Sooner than later would be best. Good luck!
