God Bless you. I have been there! See a Nuerologist. See an Othopaedic Surgeon. Consider seeing a Sports Medicine Orthopedic Specialist. All for diagnostic and testing reasons. Question: Could you have pinched nerves somewhere? Is there an injury they have not yet identified to the lumbar spine? Could pressure from the cervical spine be causing pressure on the spinal column thus giving you pain in the lumbar area? There are several tests other than the MRI that can identify problems. A teaching hospital where they are constantly dealing with the odd problem would be a good resource!
