One of my worst symptoms during lyme was my tight jaw. It would cause tooth pain, headaches, etc. After 6 months of abx it is gone! I went to chiro, dentist, periodontist, etc. and they all told me tmj. It wasn't for me, just tight muscles caused by lyme and lyme anxiety. Xanax also helped relax me and helped a little with anxiety. My face would also be numb on right side which is same side as tight neck and shoulders. Best of luck to you.
P.S. peppermint oil - to put on jaw or pill??
