Hardened Skin
Nearly all cases of CREST syndrome cause the development of patches of hardened and thick skin on different parts of the body. Commonly affected areas include the legs, torso, face, arms, and hands. Those spots might look like straight lines or ovals. They can show up as a line down your leg or arm. Depending on the kind of scleroderma, the size, location, and the number of skin patches can vary. The face might look mask-like or waxy as well. These changes could affect your movement and make it harder to bend your toes or fingers. [3]
