See a rheumatologist: Please consider seeing a rheumatologist for a second opinion. There are certain inflammatory arthritic disorders of spine which are treatable. If nothing else, you will get an accurate diagnosis and know your treatment options.

Back pain needs: to be evaluated by your doc. After that you can use cognitive therapy to help change thought patterns and reduce/relieve pain. See the work of John Sarno, MD about a mind-body approach to resolving back pain. Peace and good health.
