You're just worried it's dislocated. Take it easy. If you dislocate it, you can't talk and eat normally. It's just edema of soft tissue or ligament, which will recover after a while.

Supplement: Ligament injury is affirmative, and it is also a jaw fracture. Don't worry if the food you bite doesn't feel torn.

As for the ear, if there is swelling and squeezing pain, please go to the hospital immediately. Also, don't trust some hospitals and clinics on the Internet. It is best to go to a local regular hospital for medical treatment.

Finally, I wish you a speedy recovery.
