Oh gosh! hey there! I have VERY little internet access however i would of replied in a heartbeat!
Your story breaks my heart honey but the good news is that you had success with the splint so we know you can become 100 % again!
First advice is say bye bye to that horrible doctor who refuses to give you an MRI now!!!! go to the emergency in your hospital if you have to but you MUST get this MRI!!!
I seriously would go to emergency and they can immediately see you, thats what i did and it was only there i was diagnosed with the correct disorder of tmj!
Hang in there honey! i promise you this will improve , you just need your mri's!!! Please let your doctor know how disappointed you are in her negligent calculus and she has to know how selfish her decision was .. shes not suffering... some doctors are evil like that

! AN MRI is urgent here! everyone is here for you!
how are you feeling now... you need oto get the MRI , more scans and a good dentist in that region! please advise me how your diagnosis is!!!!
Thinking of you honey and praying! You'll make it , never give up ! have hope!
