The million dollar question! But, I did try. In Aug 2019, I went so far to have targeted injections in the L-4 -L-5 area, the following day, pain level below one. It was an epidural lumbar spinal injection and my walking for 3 days improved 50%. Had second treatment a month later, got 5 days. Because the relief didn't last longer, the pain management anesthesiologist would not do 3rd injection. My neuropathy did not go away but decreased. Boy, those five days were terrific. My problem is that when a doc sees me walk in with supports and a cane... yet I do walk in on my own, I think they are afraid to do a procedure making me worse off than when I walked in. So, the spine problems continue along with the PN. Any connection or simply a coincidence??

Probably because the nervous system runs through the spinal cord and nerves do not like it when they get compressed or damaged by spinal issues. At least that's what this side of the peanut gallery thinks. 🙃
