If you have diabetes, look at your feet every day, even when they feel fine. NIH's National Institute of Diabetes and Digestive and Kidney Diseases says you can have foot problems and feel no pain, and a daily check helps you spot trouble early before it gets worse.

The reason is nerve damage, the institute explains. Over time, diabetes may cause diabetic neuropathy, which can bring tingling and pain or make you lose feeling in your feet. When that happens, you may not notice a pebble in your sock or a blister on your heel, and those small things can lead to cuts and sores. Cuts and sores can become infected.

Diabetes can also reduce blood flow to the feet, the institute says, which makes a sore or infection slow to heal. An easy habit is to check your feet each evening when you take off your shoes, including between the toes. If bending over is hard, use a mirror or ask someone else to look.

The institute also advises wearing shoes and socks at all times, even indoors, and asking your health care team to check your feet at every visit. It recommends a thorough foot exam at least once a year. Talk to your doctor about what is right for you.
