Mine is in both feet. I was also told "end of the rope" but still kept looking. I found a foot doctor in AZ that did not give up on me. He prescribed EB-N6 a month ago. I now have more feeling in my feet and cut my Pregabalin by 1/3. In a couple of weeks I will try reducing it some more. This has been a godsend for me. Perhaps it could benefit you.
