Hello. You asked for success stories. I also have PN, from two surgeries on my ankle. It went up my calf. I started on B vitamines including b12 shots over a year ago now. I have definate improvement with this condition. Still numb in areas, but some of the ouch of the pins and needles is gone. I am still hoping for complete remission. I see a physiatrist, who is treating me with pain issues. I wish you all the best. ginnie
