About three weeks ago I woke up and my left jaw bone was very painful and stiff. Even my teeth hurt. On most days this eases up and is very tolerable. But some days it is still and very painful all day, causing headaches and extreme ear pain. Is this TMJ or what. On the night beofre this accurred, I fell asleep on my stomach and slept almost all night on the left side of my face. Sometimes damp heat helps.
Dear patient Considering your case source of pain is mostly TMJ sprain or early arthritis. This needs to be investigated with X-ray of TM joint.  Visit radiology center nearby you and get it done. Meanwhile, start tab diclofenac 50 mg twice a day for pain relief. You need to consult expert ENT specialist with X-ray report.  All the best.
