Have you seen a neurosurgeon?
When nerves are involved that may be the best way to go.

I had a hemilaminectomy and forominotomy in 2006.
Now I have ongoing pain and neuropathy in both arms and hands.
According to the surgeon the surgery was a success and I have other causes for the symptoms.
Recently I was diagnosed with Myofacial Pain, and that accounts for the nerve problems.
My pelvis, neck and lower back are all involved.
You fix one thing and then have another to contend with.

I wish you the best in finding the proper way to go.
