Suggest Treatment For Pain In My Cheek And Jaw

I have had pain in my check, jaw and in front of the ear and jaw for 7 weeks now and have been given 3 lots of different antibiotics but nothing is helping. I am on strong pain killers and have ruled out dental problems I feel fine other than facial pain and what feels like constant ear pain and nerve pain in my arms now and again along with neck pain could it be a trapped nerve?
