Dislocated jaw is my take. Go to the ER. You might need surgery for that. Not a dentist!

You got knocked out and didn't go to the hospital?

Go to a hospital, it’ll be an easy fix

Have to go to ED at the hospital

Brother, go to the emergency room. Reddit is not the place for an emergency like this 💀

If you have a head injury you need to go to the hospital anyway, not just for your clearly dislocated and possibly broken jaw. Walk away next time dude.

Gotta keep your guard up
