I’ve actually had this problem for a couple years now, but It has gotten worse recently. There is a spot on the arch of my right foot just to the side of the part of the arch that makes contact with the ground that in the past has periodically itched. Scratching it seemed to help, and it was never a big deal, the only thing noteworthy about it was that it kept coming back periodically.
