Had C3 VAD after a chiropractic with TN, GPN severe along larynx/pharynx and have pain near jugular to clavicle then chest pain along right sternum to diaphragm and right rib with pain to inhale in my chest wall. Have hard belching when sternum pain is peaked same time as throat pain then acid release back of throat with pained tongue. Also have compressed spinal cord C 5-6. Often get chills after a severe episode. Had cluster headaches after that chiropractic adjustment and relieved 3 years after when that bone moved. Swelling right face and hot redness relieved as well as facial spasms too when it moved by self adjustment with hard head turn. Stuck with TN and GPN though and this chest pain is painful but not a concern to my neurologist. The C3 VAD left me with facial weakness and droop but no brain ischemia so this also is confusing without explaination. Any ideas? Is the vagus nerve involved? I heard VGN has all those advancing GPN symptoms mentioned. many medications sensitive too. Next is Cymbalta and larynx injection.
