Update after the myelogram.
After 4 years I have an answer

My persistant back pain is from 2 arthritic and degenerative disks. Which explains some of my feet pain. We are going to try a facet block next week to see if it provides relief. If not my choices appear to be more medications or lumbar spine surgery.
My nueropathy is considered Critical Care Nueropathy so treatment there is the same. I'm curious what my feet my feel with the Lyrica if my back ever calms down.
On the bright side the Dr ruled out Arachnoiditis as the main cause of my pain. There was a small amount but not enough to cause my pain.
For the first time in months even though I hurt I feel like there is hope beyond taking medications.
It took me 4 Dr's to get to this point. I still think the 1st Nuero I saw wasn't interested since he was leaving the practice shortly after I saw him. One bright side is my Pain Dr's were on the right track so I got that going for me.
