Dan, get this checked out. Also, this can be a classic sign of vitamin deficiency ...especially the B vitamins. Go get this checked so you can nip this in the bud and it doesn't progress in case it is a vitamin/nutritional issue..
Blessings and Best Wishes! Shelly
I'm a 52.5 yr. old female with chronic illness ... exercising and riding a bike daily! : )
I've not experience numb legs, but I sure do experience "cold" legs. I have started wearing pajamas to bed for my cold legs. I'm fine elsewhere so I can't add blankets or I'd be too hot.
