Do I have a wart on my foot?

Maybe. A growth on the foot that might resemble a wart could be a clogged up sweat gland on the bottom of the foot. There are roughly 250, 000 sweat glands on the bottom of each foot. What might look like a wart could be a clogged up sweat gland, a callous, or a skin cyst. The Healthmark doctors know how to make a proper identification of what dermal formations are present on your feet.
