PAD Symptom: Non-Healing Arterial Ulcers on Feet

Foot Sores and Ulcers That Won’t Heal

If you have foot sores that won’t heal, we want you to know these may be signs of an underlying health condition. While only a medical professional can accurately determine what is going on, one potential cause of foot sores that won’t heal is peripheral artery disease (PAD)

PAD is a common, yet serious, disease that can impact your ability to walk, climb stairs, and fully participate in daily activities. It can also cause a range of painful symptoms and place you at increased risk for heart attack, stroke, and limb amputation. 

At USA Vascular Centers, we specialize in treating PAD ulcers and other symptoms of peripheral artery disease. We believe that personalized treatment by our expert vascular specialists can help you regain your mobility and daily routine. 


What Are Arterial Ulcers?

An arterial ulcer is an ulcer (an open, non-healing sore) that develops due to inadequate blood supply to the area. Most commonly, the legs, ankles, and feet are affected. 

Arterial Foot Ulcers

Arterial foot ulcers are open sores that are slow to heal or keep returning on the lower legs and feet. They are often found between or on the tips of the toes, on the heels, on the outer ankle, or where there is pressure from walking or footwear. If you believe that you have arterial ulcers, we recommend visiting a vascular specialist.

How Does Peripheral Artery Disease Cause Arterial Ulcers?

Peripheral artery disease can develop when excess fats and cholesterol circulate in the blood. These substances can begin to build up on the walls of the arteries, forming a plaque. This plaque can lead to a narrowing or complete blockage. When the blocked arteries involved are responsible for delivering blood, oxygen, and nutrients to your lower extremities, you may develop PAD symptoms like leg pain, cramping, and fatigue.

Although PAD symptoms affecting mobility are most common, there are other issues to look out for, too. When blood is unable to reach your legs and feet, you may notice problems like regional numbness, coldness, poor hair or nail growth, and skin discoloration. Over time, areas of the skin can become inflamed, break open, and form PAD ulcers

Arterial Foot Ulcers vs. Diabetic Foot Ulcers: How Are They Different?

We want you to understand that having foot sores that don’t heal doesn’t necessarily mean that you have PAD. There are several underlying health conditions that can also cause decreased healing in the feet, including diabetes. 

Individuals with diabetes can develop diabetic foot ulcers, which are different from arterial ulcers. This type of ulcer usually occurs due to neuropathy (nerve damage), which can desensitize feeling in the foot. According to Dermatology Advisor, diabetic foot ulcers tend to develop on the bottom of the foot, most commonly on the first metatarsal joint or the heel of the foot. They are not always painful; in some cases, patients are completely unaware that open wounds are present. 

Arterial foot ulcers develop due to poor circulation from peripheral artery disease. Although arterial insufficiency ulcers can appear anywhere on the lower extremities, they most commonly occur on the toes, heels, and ankles. They are usually painful and can be yellow, brown, gray, or black in color.

It is important to know that diabetes is a known risk factor for peripheral artery disease. Diabetic foot ulcers can be further complicated by the presence of vascular disease. If you have diabetes, we suggest working closely with your doctor to properly manage it. This may also help reduce your risk of developing vascular disease.
