The heels of my hands are cracked and painful. Sometimes they itch terribly, bit it feels as if the itch in under the skin, not the skin itself. Sometime I can scrape dry skin off. Could I have psoriasis? or what do you think? My doctor had me try a clotrimazole cream, then prescribed Betamethasone Dipropionate, but neither seemed to help. I am a white, 60 yr old female. Thank you.
