I wanted to reply to you and let you know that you may not worry that you have waited too long! I had tmj really bad for 9 years(1991-2000). I had clicking, terrible pain, lockjaw, and problems lining my jaw up correctly in order to open my mouth. It was awful. I didn't know what to do. In 2000, I moved from Delaware to California and after one month, my TMJ disappeared and has been gone for a little over 3 years now! I came to the conlusion that mine was totally related to stress and taking myself out of the environment I was in and becoming very happy made it all go away. Depending on what kind of TMJ you have, maybe that could be a reason. Do you have any stress at all that might be causing this?
