Ever since I was a child, there are times when I get really
itchy feet, especially the tops of the feet and the ankles and lower shins/calves. Small scabs develop in these areas where the itching occurs (perhaps due to scratching), but eventually it all goes away (maybe a matter of days, weeks, even months). I've never paid much attention to it, never done anything about it, I usually just try to ignore it until it goes away.
