Owwwww

I have no idea what I did, but I woke up Friday morning with the top of my left foot hurting. Any sort of pressure, to include the bend/flex of walking, hurt. As of last night it appears slightly swollen, but not significantly, and there is no bruising. Its still bothering me even today although its less now

I just can't figure out what I did unless I kicked something in my sleep...and I don't know what I'd have kicked that would make it hurt but not leave a bruise even several days later.
