Dissatisfied

I had an accident last year in December, I sent request numerous times whilst I was admitted in hospital for an MRI and I was told different things by different people the specialist and the Physician also sent through motivation and also to give the motivation for the urgency of the MRI unfortunately my medical aid could not help even though they said seeing that I was an inpatient it should be done. I know have a terrible pain that will not go away, I have taken different types of drugs to alleviate the pain and unfortunately nothing seems to work and the unfortunate part is that oRTHODONTIST WAS NOT 100% SURE WHAT IS IT I needed. what is it I should do.
