I often get these symptoms:
Tight/sore muscles in neck & shoulders & jaw ( Clenching )
Pressure behind eyes & sensitivity to light <-- Most annoying symptom
Difficulty concentrating

I have found that I can reduce these by simply relaxing for 20 minutes, but that doesn't last forever and they eventually come back.

Does this sound like TMJ? - I've never seen a dentist for this, I actually haven't been to one in 2 years - anyone have any recommendations for a dentist in Boston, MA?
