Hi. I Have White Blotches Of Crusty Skin On My

Hi. I have white blotches of crusty skin on my arms, legsand now on my head under my thick hair at the bottom of my scalp. These do not itch, do not weep or hurt. They and are lateral on both sides of my body. When one starts up on the left forearm a few days later there will be a patch on the right arm. Any idea what this is? I am 65 and have always had good skin. my email is YYYY@YYYY

THANKS
