[/INST] HI, I have read your problem. You might be suffering from sub mucous fibrosis while chewing tobacco since last five years that way your mouth will not open much. In addition to this you might be having wisdom tooth problem. You have not mentioned age which is important for wisdom tooth eruption, in that way you are having problem in back jaw, gums teeth, neck and ear. Go to any ORAL SURGEON clinic, he or she will guide you better. After taking OPG x-rays they can tell you better what is the problem. If this is because of wisdom tooth, they can plan for extraction of that wisdom tooth under general anesthesia under antibiotic, analgesic,trypsin, chymotrypsin and b-complex. For submucous fibrosis, treatment is possible by giving some injections of steroids and through exercise also. But to quit habit is the first criteria. </s>
