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.
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.
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.
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.
