I get sharp/pulling pain in the underside of my tongue, which then extends to my lower jaw bilaterally, sometimes recently, my upper jaw, then goes down my throat, like a pressure/tightness, and continues to my upper chest as a pressure/pain. It comes on anytime of day or night, not doing anything specific, could be nothing, talking, waking, etc. Lasts a few minutes each time. Could happen multiple times a day or not at all for days or weeks. Had a checkup with my primary MD, a visit to the dentist, bloodwork, EKG, Cardiac stress test, everything ok. Any ideas?
