Have you tried taking Neurotin or Lyrica? I have neuropathy and it has recently spread very quickly throughout my body and the only relief I am able to get is with Neurotin (generic is Gabapentin) and without it, I can’t function because of the pain and the feeling of a heater being placed against my feet and my legs going numb and feeling very heavy and making it hard to walk. Mine started from a car accident but I’m being tested for Lyme Disease because of the rapid increase of nerve damage throughout my body. If you’ve never tried those meds, I would definitely recommend it before taking a chance with a procedure that may cause more damage. Best of luck to you and I hope you feel better soon!
