I noticed my right foot has a slightly darkness under it and it itches from time to time. I also noticed some dry skin around the inside of the same foot. I wear black boots to work with black socks. Anyone have an idea what this might be?
wear sandals for a few days. if it goes away- it's athlete's foot, or one of the fungals, anyway. OTC sprays work fine if it's not a real infestation (cracking skin, noticable odor)
if it doesn't... it could be a plantar's wart.
