To explain what is wrong... Hmmm, hard to say. I've had this before, several times. It's not a sprained ankle, but more like something that hapened to the top of my foot, so that flexing my foot up or down hurts the top of my foot like crazy. I don't know if it's a muscle, tendon, pinched nerve or what, but something is snapped out of place. I don't think there's much I can do about it but wait.
Meanwhile, I think I am going to have to skip my workout tonight. I would really like to do it, but I don't see how I can do the treadmill, bike or stairmaster, since all of them involve the foot and ankle. The only thing I could is lift weights but that seems pointless since I'm out to burn calories, not get buff. Too bad, since I just bought myself a pair of those knee-length spandex workout shorts -- the end of chafing, I hope.
I think I'll getting hopping (ha ha) on dinner, then maybe soak my foot in hot water with something like lavendar in it.
