Patient: I have dry skin to begin with, and I always itch my legs(only my legs) so I have been put on a steroid creme for years now but its just not doing the trick. Recently I gained only one at a time a dry circular patch of skin that I itch so much. The first one I got was at the end of winter last year on my lower left side of my calf on my left leg, the one I received now I have six inches above where the first one was. Should I get this checked out? What is it?
