<s>[INST] hello doctor,for past 2 days i am getting pain on my right side of my jaw when i open my mouth only.this pain seems to be right below my ears . this pain worses when i keep my mouth shut for a long time and then open it for first time . what should i do and what medication must be taken to cure it . [/INST] Hello, Your Description sounds like it may be in your joint called the TMJ. Some anti-inflammatory medicine is recommended. Try a soft diet as well. Do you hear any clicking or feel your jaw shift to one side when you open? There is a disc that can be not moving correctly or damaged in this joint. Stress on this joint can occur from trauma, grinding one's teeth or an unusual use.  If it persists or gets worse, consult an oral surgeon for a Andrew X-ray which will show the jaw. This is my suggestion to start unless you can provide additional details and symptoms. I would be glad to help you further. I hope you find some relief. </s>
