I'm having the strangest thing happen. When I get up in the middle of the night, the very bottoms of my feet HURT - and I mean really hurt. Almost to the point of not being able to walk on them. Sometimes it feels like I'm walking on hot needles. When I get out of bed in the morning, it is pure torture to walk down my steps to the kitchen, but my strong desire for coffee prods me on... Anybody else experience this, and if so, is there anything that can be done to stop it?
