The the fact remains that you can sleep at night.
Many of us with PN pain cannot.

I don't think you are going to find a solution now...since you have been down so many roads. The only thing you have not followed up on is infectious disease specialty.

I'd see if you can get that special MRI en bloc describes. It shows damage to the dorsal roots if it is there. If you have that, then there really is no treatment as of yet. You'll just have to hope for healing. (that is where the supplements may come in).
