Diabetes raises your risk of infection and slows healing, so treat even simple cuts and scrapes quickly. Properly clean your wound and use an antibiotic cream and sterile bandage. See a doctor if it's not better in a few days.
Check your feet every day for blisters, cuts, sores, redness, or swelling. Moisturize them to prevent cracks. (But don’t rub the lotion between the toes!)
