my head hurts really bad but only on my left side, it started out just being tooth pain on the top and bottom of my jaw, i even went to the emergency, after that a few days after i was at the dentist, the dentist said he couldnt see nothing wrong with my teeth just that my gums looked a little irritated. but the pain gets so severe that it has me in tears, its so painful, now like i said the pain almost feels like a migraine but ive never had one of those, its mainly in my left side right in my jaw, eyes hurt when i focus, headaches, neck pain, and im expecting if that helps
