overwhelmed

I am new to this site and not sure I am doing this correctly but would love any input or suggestions to my situation.  I have had chronic facial pain since april 1996. It started with burning tongue and then led to bilateral neck which felt like swollen glands.   I have been thru every possible Dr and was basically diagnosed with facial neuralgia.  I was on Methadone for 10 yrs (after everything was ruled out) and for the most part out of pain and feeling normal.  I went off of it with a new Dr in january of this yr so I would feel if the injections he wanted to try would work.  That is when my teeth and jaw started hurting.  I cancelled the injections so that I could get my teeth examined and get whatever was needed to be done before the injections.  Well, when I cancelled, he assumed that I was only wanting medication and dropped me as a patient.  Now it feels as if all my teeth are aching and squished together, but there is nothing wrong with them.  I was in a 2 car accidents 20 yrs ago, both face trauma, one to my bottom teeth and the other to the left side of my face.  Now my jaw aches constantly along with my teeth, I don't have any popping or any noises when I talk or eat but I do have alot of muscle pain in the right side of my jaw, underneath my chin, my neck, my ears and sometimes my right arm aches.  I am doubting the neuralgia now and have an appt with my dentist (yet again) to get a referral to see if this is TMJD.  Is there hope for the disorder or am I forever stuck in what seems like hell?
