Many years ago, I had root canal surgery with postop symtoms similar to yours. My endodonist couldn't understand the continuing terrible pain. He wrote to the journals, etc., but received no help.

Years later, I ran into him and he told me he had finally found why I had so much trouble and that there was now help from my neurologist. My neuro gave me neurontin for peripheral neurapathy. It was supposed to help with pain but all it did was cause my eyes to blur, so I stopped taking it. After talking with the endodonist, I tried taking one pill when I had a bout with recurring jaw pain. Boom! The jaw pain stopped, I stopped the neurotin and didn't take it until next time. Same results.

You might ask your neurologist about neurontin or something similar. You might have developed PN with all the insults to your nerves during surgery.

Good luck in dealing with this. Antibiotics did me no good, either.
