A skin problem is sometimes the first sign that you have diabetes. One of these skin conditions is eruptive xanthomatosis, which can make hands and feet itch. It’s caused by out-of-control diabetes, and it goes away when the disease is managed well. It can also make you itchy on your arms, legs, and buttocks. Other signs of eruptive xanthomatosis:
- Small, yellow bumps on the skin
- Redness around the bumps
- High cholesterol
