my husband is diabetic, although not insulin dependent. He has a permanently dislocated ankle (from time of Vietnam war) that he started wearing an Arizona brace for. The brace helped tremendously. He could walk without pain. However, he liked it so much that he wore it for 4-5 days and nights without taking it off. He developed what looked like a red rash around the ankle, and also deep cracks in his heel. He stopped wearing the brace to allow all this to heal. It has been about 5 days and the original red spots and cracks are nicely healing but there are new outbreaks of the red spots that look like they follow veins. He also says that they itch. Do you have any idea what this might be?
