Dear there the information of pain and problem stated is quite not enough to guide you properly Though would like to add that visit an appropriate specialist  dentist asap

It could be due to deep bite or bcoz un balanced occlusion where the condyles are not closing properly. U need take one OPG and consult one oral medicine and radiologist. Use pain killer n soft splint would be beneficial

You need to visit the dentist for a proper clinical evaluation and TMJ view X rays will be required for assessing the damage that has happened to the joint. The right treatment can be suggested after that. But we prefer to follow only conservative methods when it comes to treating tmj arthrosis. Most likely you will be advised night Guards to be worn daily so that the forces being borne by the joints can be buffered. Regards

TM joint pain with clicking happens when the disc is not synchronous with condyle movements per se. The joint mechanism is such that when you chew on right side the left joint gets maximum load.
