Cramps at sides of feet
I've had this problem since 2008 at least, and I have no idea what it is. The sides of my feet (about where number 4 is in this image, though not quite so long, only about an inch, maybe more, near the smallest toe https://upload.wikimedia.org/wikipedia/commons/5/5d/Foot.png) cramp up real bad. The cause of the cramps seem to be random, sometimes it can be a certain way I move my foot or even my leg (and what causes it once may not cause it again), other times it just comes out of nowhere. I get very little notice, I can feel that part of my foot start to cramp up and a second later it's rock hard and painful. I instinctively angle my foot downward which alleviates the pain somewhat. If I hold my foot in that position long enough it'll slowly go away (I have to be careful, if I start to return my foot to a normal position too soon it cramps right back up again). Once it un-cramps the pain is typically gone, but I can usually feel the muscles in that part of the foot moving for a short while afterward.
It's rather problematic, especially when I try to sleep. I've had trouble sleeping due to this issue before because my feet will repeatedly cramp up while I'm trying to get to sleep. I have no idea what the problem is, I don't think it's pressure related as it happens when I'm not on my feet, even when I've barely used my feet that day. I don't think it has anything to do with shoe size either. Has anyone experienced anything like this before?
