You need to visit an oral and maxillofacial surgeon who will examine you properly and if required,  perform TMJ Arthrocentesis or other procedures usex to cure internal derangement. 

Hi visit a dental college .. their they wil give u tens therapy

Dear sir Your problem of disc displacement is something you need to act seriously upon. I suggest 2 things. 1)visit a TMJ specialist who would ask you to get a CBCT done along with evaluation for why this condition occurred in first place. Since there are various reasons dental or skeletal. 2) Further the  CBCT reports and TScan evaluation would help in getting the correct treatment planning done and executed.

Hi Did any of the dentist you visited suggest an X-ray of TMJ?? If no...get one done right away before consulting another one. All the best
