Arms and legs falling asleep
you have new pressure points and less padding, get up and move around, if it contiues call doctor, move, and keep moving, watch hard seats, and sitting too long in the car. as you loose more you will want to fidget, but the sking is in a different place, and bones poke thru closer to the surface. Good Luck
that was my first thought, as well. What's your B12 level? Above 400, at least? If not, that's a factor.
Please note: I AM NOT A DOCTOR. If you want medical advice, talk to your doctor. Whatever I post, there is probably some surgeon or other health care provider somewhere that disagrees with me. If you want to know what your surgeon thinks, then ask him or her. Check out my blog.
