question: Hi. I have small circular patches of skin on my palms and feet that are skin color except around the edges where they are white and look dry. The centers of the circle are open, like a blister without pus that has popped. I m not sure that what is on my hands is the same thing that is on my feet. The circles on my feet are slightly deeper, smaller, and far greater in number. If you know what this might be please let me know! Thank you.
