Are your toes actually numb, as in you can't sense touch, or is it more of altered sensation? After a few months of my full body SFN onset (but targeting my legs and feet most), I developed this odd feeling in the three outside toes of my right foot. It feels kind of numb, but not really because I still have sense of touch.

When I reading about SFN one day, I read an article by a doctor who described it best..."It feels like your socks are bunched up under your toes." When it first started, that's exactly what I thought it was. After a half-dozen times of checking my sock, I realized that wasn't the issue.
