When I got what my Dr. called a "fissure" in my heel from a cracked callous, he told me to use a lotion called "Amlactin". It's not a prescription lotion, but I did get it from my pharmacist. It worked like a miracle! The crack was so painful it hurt to walk - and since I am a diabetic, any foot thing is scary - and the Amlactin softened my heel overnight! It worked on my fingertips too. I'm kind of picky about lotions, and I have to say that I didn't like the way it felt on my hands, but boy does it work! My "usual" hand/body lotion is "Udderly Smooth" udder cream - not greasy or smelly & soaks in really fast & doesn't make my hands feel sticky. Hope this helps!
