Ulcers, or open skin sores, can develop anywhere on the body, including the legs and feet. They may signal an underlying condition and take a long time to heal.
Ulcers can be caused by an injury that breaks the skin, too much pressure from shoes that don’t fit properly, or extended periods in bed. Anyone can develop an ulcer, but they occur most frequently in patients with diabetes, neuropathy or poor blood circulation.
Symptoms may include a strong odor, drainage or thickened, inflamed tissue. Pain is not always present. Foot and toe ulcers are often crater- or wedge-shaped and can grow from pea size to encompassing the entire foot.
Foot ulcers can range in color from yellow, pink or red to gray, brown or black. Most serious is black, which indicates gangrene, a severe condition that requires immediate treatment.
Diagnosis may include X-ray, CT scan or MRI to evaluate for bone infection or to detect other conditions that may make it more difficult for the wound to heal.
Foot and leg ulcers are treated by removing the unhealthy tissue and performing appropriate wound care. Special shoes or padding may be recommended to remove pressure on the area.
If infection is present, antibiotics will be prescribed. In severe cases that involve extensive infection or are slow to heal, advanced wound care or surgery–including amputation of the toes or foot–may be needed.
If you have diabetes, it’s important to see a foot and ankle surgeon regularly. Diabetics are more likely to have poor circulation in their feet and legs, as well as nerve damage. As a result, they’re prone to developing ulcers on their feet and may not even feel them.
Whether you have diabetes or not, you should see a healthcare provider immediately if you find an ulcer on your foot or toe. Left untreated, ulcers can lead to infection in the skin and bone and serious complications.
