ok i have problems with the skin on my feet, the skin is really hard and peeling on the soles of my feet and i know that its not callouses because im fairly immobile. what could it be? its not athletes foot because it doesnt itch or burn and its not red, its more like a grayish color, its really irritating me, when the skin starts to peel off, if it gets caught on something it hurts like hell, what do i do?
