Check your feet every day for sores, calluses, red spots, cuts, swelling, and blisters. If you cannot see the bottoms of your feet, use a mirror or ask someone for help. Keep dry skin lubricated. Do not put your feet into hot water. Do not smoke.
Smoking affects the small blood vessels and can cause a decrease in blood flow to the feet.
This makes wounds heal slowly. Never walk barefoot. You could injure your feet and not notice it. Keep slippers by your bed to use when you get up at night. If your feet are cold, wear socks.
