Re: I'm confused
There could be a whole list of things that could be causing your pain..Your body is feeling it, so there is a cause to it.
I agree with GT about a second opinion....It may not be TMJD; but, there are muscular disorders that could be resulting in pain, especially near the joint. All of our muscles are interconnected...so, of course, tight muscles in the neck could affect your head and vice versa.
Have you ever considered Chiropractic/massage/accupunture. For some, these things help.
If you are in pain, there is a reason for it. And, since it is on your mind, a second opinion may be warranted.
