I just did a search for TMJ in the UK and came up with only one half decent link (as a basic google search, I know if I start with the British Medical Journal site etc it will get better) but here is the kind of overall feeling I get about it
http://www.addenbrookes.org.uk/serv/clin/surg/oral/tmj.htmlthe hot towel, anti depressants, resolving any stress, splints etc surgery, hardly mentioned. I am sure it *is* done, but the prevailing attitude towards it seems to be very matter of fact, almost get used to it, overcome it.
I hope someone comes along with an entirely opposite viewpoint/experience for you, because I understand the pain- although my jaw has never actually clicked out of place- I did take one bit of advice, I never chew gum and I don't open wide and eat very very chewy foods and he massaged my face and that was about it!
I am sorry it's not more positive than that, but I feel being quite pushy about being referred may get you further.
