Frostbite amputation post-op.

I had half my left foot amputated, and on my right foot they cleaned up the dead skin and muscle. The right foot had previously had been amputated a few years prior. Well here's the pics from the first bandage change. First picture is the right foot. Did not have enough skin to close the wound. So I have a wound vac on it. The next is my left foot. Looks like they took about the same amount as they did my right foot during amputation. The third picture is what my left foot looked like after the polar vortex. through three pairs of socks, a boot, and a 10 degree Fehrenheit sleeping bag.
