I have the same thing, but mine comes back eventually. Yesterday I was walking and had a vague pain in my left foot. I hadn't gone but a couple miles before my last two toes on that foot became completely numb. I continued to walk a mile or so and came home. Once I was home, the feeling came back. This was different from the previous bouts of "out of the blue" numbness. I also added sublingual B12 because I know it helps with the foot cramps I get. I don't know if it will help this or not.
