If you haven't read my post, I hope it is relevant for help. I posted under the subject "pain" right after winterbridge.
I know just how you feel. I have all these symptoms and have been told they're all due to TMJ/Myofacial Pain Syndrome that I've been diagnosed with.
I have pain in my ears a lot. I think it's nerve damage from all the root canals I had.
Seeing an ENT and tmj specialist is advised.
