I have intermittent pain above my back teeth on just one side. My wisdom teeth have been removed. There is also a tightness in my jaw when pain is present. Sometimes it throbs at night and sometimes there is no pain. It comes and goes during the day. If pain is present, it is worse if I lean over to pick something up or any activity that increases blood flow to the area. A dentist has xrayed the area and didn't see anything. It is not sensitive to hot/cold. Any ideas on what the problem might be and what kind of medical professional should I see?
