Will my tmj ever get better?

I had and head on accident, from a drunk drive when I was 19. After that, I had many strange symptoms of discomfort (headaches, muscle spasms, left sided tmj discomfort, aching in my teeth, etc.) I've had 2 occusal adjustments to readjust my bite, in approximately 8 years (wrong thing for a tmj specialist to do; I find out know). Now I am 38 years old and for the last year have had severe discomfort in my left tmj area. MRI scan shows complete slipped disk in the right tmj. Been treated with splints to readust my bite, related to my bite shifted. Now I'm on muscle relaxants, pain pills, and celebrex(antiimflammatory med.). Looks like I'll need to where a splint all the time (24hrs a day); cause discomfort doesn't go away; usually even with splint!!!!!!!!!! What do I do next?????????????????
