OP: It is not permanent, I had a horrid case of PN and now it's hardly noticeable...except my thigh is numb from a messed up hip replacement, and the pins and needles are from this too, and all the nerve damage. Nerves may never come back for many.

What has saved me is Inosine and Sphingolin and my great anatioxidant Grape Seed Extract...I have a lot info posted here on PN.
