a year ago i banged my chin against a rock while falling and my jaw got dislocated/fractured and a molar got chipped(i bled from my chin and both ears but only onside was dislocated/fractured). I'm better now but recently i was stretching and i yawned but i felt a weird sensation travel from my back to my upper neck but when i clenched my teeth together the molars that got chipped started vibrating and i started hearing this high pitched noise getting louder and louder and i just heard and felt a pop in my ear. Then the middle-side of my head started tingling and all my teeth started hurting and my skull felt like it was cracking in half between my eyes through my scalp, my whole body started feeling tingly/prickly like when you sit on your leg cutting off circulation but it hurt really bad every time i moved or tried to talk. Can anyone help me find out what this is? because its happened more than once and when it does there's a very noticeable pressure in the top left of my skull that feels like something is trying to get out or its swelling pushing upward. i know this thing also triggers my anxiety because i had a panic attack from all that sudden pain.
