the palm of my hands and fingers itch mostly the spot on my hand below my thumb and the base of my fingers-middle and ring fingers, both hands. They get a sticky type of oozing small blister type of yuckyness and ultimately end with open huge cracks that hurt like crazy and ITCH!!! I have not changed shampoos or soaps, everything is the same as I have used for years. This started about 3 years ago. I have tried over the counter ointments and creams as well as RX and nothing is helping. Any suggestions?
