I understand how painful that is. I used to wake up and found out I unconsciously scratched my athlete’s foot and so it went really bad. Anyway, I was able to treat it by using gris-peg. It’s an oral medication. Ask your doctor about it so that you’ll have more information. It’s also available on any
pharmacy out there. In addition, make sure that you keep your feet dry and clean. Don’t wear any shoes or socks without your feet dry. Hope this helps!
