Hi and welcome to HCM.
It doesnt seems like something serious and it should pass in a few days. you probably had head,jaw and inner ear contusion
. YOu should rest in dark room, avoid noise and lights, apply some cold compresses on face and take standard pain killers. If you notice deafness
, buzzing in head, nausea or vomiting
you should visit doctor. WIsh you good health.
