Pressure sores can develop when skin and deeper tissues experience prolonged pressure, especially along the legs, heels, or ankles. These injuries often begin subtly, starting with redness or tenderness before progressing to open wounds that are slow to heal. People with limited mobility, diabetes, or poor circulation face a higher risk because their skin is more vulnerable to constant pressure and friction. Prevention begins with awareness. Regularly checking the legs and feet for early signs of irritation can make a meaningful difference. Choosing supportive footwear and ensuring proper cushioning during rest can also help reduce strain on bony areas. Even small adjustments, like shifting your position throughout the day, may help protect delicate skin. If you notice persistent redness, swelling, or any skin breakdown on your legs or feet, it is suggested that you see a wound care specialist for an expert evaluation and appropriate care.

Pressure Sores, Pressure Ulcers, and Arterial Ulcers Can Lead to Skin Breakdown

Not all wounds on the feet, ankles, and legs are the same. Pressure sores, pressure ulcers, and arterial ulcers may look similar at first, but develop for different reasons and require specialized care. Understanding these differences is key to proper treatment.

Pressure sores are often caused by friction at common rubbing points. Toes rubbing against each other can create small raw areas, while wearing ill-fitting shoes may lead to sores on the heel, ankle, or sides of the foot. These injuries usually begin at the surface but can quickly deepen if ignored.

Pressure ulcers, sometimes called bedsores, occur when the skin and tissue are compressed between bone and an external surface for long periods of time. On the lower extremities, they frequently appear on the heels, ankles, calves, or shins. Limited mobility, tight footwear, or prolonged bed rest can all contribute to these ulcers, which may progress through multiple stages from redness to open, infected wounds.

Arterial ulcers are different in that they result from poor circulation. When blood flow to the feet and legs is reduced, oxygen and nutrients cannot reach the tissue. Even small sores on the toes, heels, or shins may become painful, deep ulcers that heal very slowly. Unlike friction-related sores, arterial ulcers are directly tied to vascular health and often signal an underlying circulation problem.

All three types of wounds demand professional attention. A wound care specialist can determine the cause, relieve pressure, improve circulation when possible, and use advanced techniques to promote healing.

If you notice a sore on your foot, ankle, or leg that is slow to close or worsening, call us for timely care to help prevent serious complications and preserve long-term mobility.

Blisters on the leg can appear for many reasons, and understanding the cause helps guide proper care. Friction is one of the most common triggers, especially when skin rubs against a brace, tight clothing, or footwear that reaches the lower leg. Heat and moisture can also weaken the skin’s surface, making blisters more likely. Some blisters develop from contact reactions, such as poison ivy or irritants applied to the skin. Viral or bacterial infections may lead to fluid-filled lesions as well. Circulatory problems, including arterial or venous disease, can cause fragile skin that blisters easily, sometimes even without injury. Certain medical conditions, like edema, eczema, or autoimmune disorders, can also contribute. Blisters can open the door to infection, especially for people with underlying health issues. If you have such skin eruptions, it is suggested that you see a wound care specialist for an evaluation and appropriate treatment.

Why Blisters Can Be Risky for Leg and Foot Health
Blisters are small pockets of fluid that form beneath the skin, often as a result of friction, pressure, or burns. On the feet, ankles, and legs, they are particularly common because these areas endure daily stress from walking, running, and wearing shoes. While many blisters are minor, they can become serious if not treated correctly, especially in individuals with diabetes or poor circulation.
Friction is the most common cause of blisters. Shoes that are too tight, too loose, or not properly cushioned may rub against the heel, toes, or sides of the foot, leading to painful fluid-filled bubbles. Activities such as hiking, sports, or even long periods of standing can also trigger blisters, especially when combined with moisture from sweat.
Other blisters may form from burns, allergic reactions, or underlying medical conditions. On the lower extremities, blisters that break open expose the skin to bacteria, increasing the risk of infection and complicating the healing process. If a blister appears on the ankle, heel, or shin, it may interfere with walking and daily mobility.
Proper care begins with protecting the blister. Keeping the area clean, covered, and free from further friction supports healing. However, large, painful, or recurrent blisters often require professional evaluation. For patients with compromised circulation or nerve damage, even a small blister can turn into a much larger problem if ignored.
A wound care specialist can determine the cause, provide safe drainage if needed, and apply advanced dressings to promote recovery. They can also recommend changes in footwear, activity, or skin protection strategies to prevent future blisters.
