Neuromuscular dentistry?

Hello all. All my TMJ problems started back in January after a bad cold. I was experiencing severe jaw popping & pain, throbbing headaches & shoulder pain, you know the usual. I went to a dentist & he assured me that he could fix all my problems. He fitted me with a bite plate & charged me $2000. Being young & naive & not doing my research, I went through with it. The jaw popping & headaches & shoulder pain have stopped, but this bite plate has caused me a whole other mess of problems. My mouth now feels very uncomfortable, my tongue doesn't know where to rest, I'm having alot of trouble chewing & swallowing, and my teeth will prematurely meet when I am talking. On top of all that, he now says I have gingivitis. I decided to read up on him online & he has alot of bad reviews and has been sued 4 times.. & lost. I'm only 18 & this has caused me so much stress & anxiety. I am now looking for another route to go & I was reading up on neuromuscular dentistry & it sounds like it will help a great deal. Any thoughts or experience with this? Please help! I just want to be normal again..
