Left jaw joint pain. For treatment.

I have pain in my left jaw since 5 months. The joint hurts when I open my mouth or chew food. The pain at times moves to the back of my ear and tonsil area also feels heavy. While swallowing, the left side of the throat feel scratchy. I have consulted many doctors, GM, Dental, and ENT and have taken painkillers, antibiotics, worn night guards, gargled with beta dine and so on but the problem has only aggravated. During one of the consultations, I got CT scan done. The doctor per the reports diagnosed gross dns with spur and recommended surgery whenever possible. In the meanwhile, prescribed to take pain killers Since nine of those meds worked, I am taking homeopathy now. But the situation hasn't improved yet. Please advise who should I consult for treatment.
