I have been having a sharp pain in my mandibular jaw, left side, for about 3 weeks. The pain is sharp and lasts only a few seconds at a time, almost like some sticks a pin in my jaw, holds it there, and takes it out. Advil and Tylenol do not seem to help. When I bend over, I can feel the pain most times, but it will come even if I am sitting still. It occurs 10-15 times a day. My left ear does not hurt, but feels "heavy"? My teeth do not hurt at all.
