I'm sorry you have not improved after the TMJ replacements. It's s**t that we get mucked around whilst being in pain, despair and depression. Often the ones who are meant to be helping us, take advantage.
I have heard similar stories about Dr Wolford before and now I will definitely avoid him.
Have you tried a nerve block? Dr Mark Piper seems pretty knowledgable about the TMJ, look him up if you haven't already.
