Welcome to the community!
I have to say, I had to do a bit of research on what TMJ (Temporomandibular joint disorder) was. I could find nothing in our resources about this. There was a lot on the internet generally though I cannot say how reliable this is.
To find out more, it might be worth contacting the British society for the study of craniomandibular disorders at http://www.jawache.com
I hope this helps.
