If its not the ear infection
, teeth or TMj then we need to go for the radiology to see if in case you got a minor fracture
, even to rule out involvement of TMJ we need to go for some investigations hope you are already through with them.
My advise for you in this regard is see an orthopaedic surgeon
, the best person to deal with your case in case of history of injury
Feel free to ask any other queries you have
Wish you a speedy recovery to health
