My socks make a buzzing noise and inflate tightly around my calves. For $800 they ought to do something more than keep feet warm. My cane hangs from my walker next to bed where I've built my nest. I have not yet figured out an exit strategy that will get me from nest to walker or cane without a groan. I have several weeks to figure it all out, but by then I won't need to figure it out - I'll be walking.
