Magnets from and MRI or another source DO NOT CAUSE anything but temporary sensitivity in SENSORY nerves, and that is primarily because of the strong current. You're overreacting, I think you have no idea what you're talking about. You continue to search and search, then, you'll find something that you can SOMEHOW relate to yourself and try to fit it in the some crazy puzzle.

Just like the picture of your back, it's NOTHING out of the ordinary, EVERYONE gets strange feelings here and there and aches and pains in between, that's part of having a nervous system. When you can A. Either feel hardly ANYTHING you step on or touch /or/ B. It constantly feels like you're stepping on piles of glass or grabbing glass THEN I would be worried.

Your doctor hasn't even DIAGNOSED you with ANY form of neuropathy, now all of the sudden you have Polyneuropathy? What in the world is going on here? You're NOT a doctor, you're trying to find ANY reason you can to have some kind of diagnosis.

I honestly think at this point a Somatoform Disorder could be the cause.
