I've got afferent peripheral neuropathy, too. Fancy name for numb feet. Mine actually feel like I'm wearing thick socks up to mid-shins. Has advantages when you stub your toe. Big disadvantage is that I can't tell what position my feet are in so I get leg cramps that wake me up some mornings. It isn't supposed to be a symptom of MS, according to my neurologist, but what is it then? Doesn't really bother me much, but it makes long walks and standing for a long time impractical. It also gets me disabled plates for my car. Magnesium and little weed seem to help.
