Hi Judy,
Yes, TMS can cause pain in other areas. It can do some crazy stuff. One way we know it's TMS is that pain due to a structural problem doesn't behave this way.
Dr. Howard Schubiner writes about chronic fatigue being a form of TMS. Have you read either of his books? If not, I highly recommend them. Unlearn Your Pain and Unlearn Your Anxiety and Depression. Both are available through Amazon. They explain all of this very well and the first one includes a 28 day program to treat your TMS that is excellent. He also has a program available online.
And, Judy, you may get more responses to your questions if you try to put them under the related Sub-Forum (e.g. Support). It can take awhile to learn how to navigate around the Forum. But don't worry about that. Just keep asking questions and participating.
