Diabetes can damage the nerve endings and blood vessels in your feet. You're less likely to notice when your feet are injured. A small problem like a callus or blister can turn into a larger sore, called a foot ulcer. Foot ulcers form most often on the pad (ball) of the foot or the bottom of the big toe. You can also get them on the top and bottom of each toe.
Foot ulcers can get infected. If the infection is severe, then tissue in the foot can die (gangrene). Toes, part or all of the foot, and sometimes part of the leg may have to be removed (amputated).
Your doctor may have removed the dead tissue and cleaned the ulcer. Your foot may be wrapped in a bandage. It's important to keep your weight off your injured foot. A foot ulcer can't heal if you put weight on the area.
Always get early treatment for foot problems.
Symptoms include an open sore on the foot that is not healing or is healing slowly. The ulcer may have started as a callus, blister, or other foot injury. It may be swollen. It may smell bad and be reddish or purplish in color. It may or may not be painful.
Diabetic foot ulcers usually occur on the bottom of the foot. They can also appear along the top and bottom of each toe. Shoes that do not fit well can cause ulcers on the sides of the feet.
Areas of the foot that have already had an ulcer may need more protection after healing, to prevent an ulcer from forming there again.
Treatment includes keeping your blood sugar levels in your target range. It also includes keeping weight off your injured foot. You may need a special boot. You may also need to use a cane, crutches, or a wheelchair. If the ulcer is infected, you may get antibiotics. The ulcer may be treated with surgery.
Your doctor will do a foot exam and ask questions about your symptoms. You may be asked about the health of your feet, including past ulcers or other foot injuries. Your doctor may order tests.
A diabetic foot ulcer is an open sore on your foot that is caused by diabetes. An ulcer forms most often on the pad (ball) of the foot or the bottom of a big toe. Ulcers can also form on the sides of the foot, tops of the toes, or heel of the foot.
