Hmmm...PN did return for me. I thought it was gone, but alas, it is not. I still take Vit B (mainly 12 is the good one) and Alpha Lipoic Acid (recommended by head of Cancer Council here in WA) . Just started reading 'Numb Toes and Aching Soles - Coping with Peripheral Neuropathy by John A. Senneff and shall report back any findings from this book.
I did a big 6km walk a few weeks back and at the end I was limping home - I almost felt I needed to crawl the lst 100m, my feet were so goddamn sore. I used to run 10km a week before BC! RARRRR!!!
