Thec. From your post, it was hard for me to determine just how many doctors you have gone to and which kind. You do mention your medical doctor and you said you wanted a neuro doctor.
In regards to your MRI. If it is a year old, perhaps you need a new doctor and a new MRI. It would seem to me that you do need a good orthopedic spinal specialist. A good pain management doctor also would help. If you continue in pain and get no satisfaction from you present doctors, search out a new doctor. Many of us have gotten opinions from multiple doctors in our research to find what is the best treatment to help our back problems. So keep looking for help. There has to be one out there in the medical field who can determine the cause of your pain.
Pain is miserable when you know what is wrong but it can be depressive when you don't know what the problem is.
Good Luck in your search.
