What it is
An arterial ulcer is an open sore that develops when the arteries do not deliver enough blood to the skin and tissue. Without enough oxygen and nutrients, even a small injury may struggle to heal. These ulcers often appear on the toes, heels, feet or the outer parts of the lower leg.
Arterial ulcers are often described as having a punched-out look, with a dry or pale base and well-defined edges. The area may feel cool, and the surrounding skin may look shiny or thin. Pain is common and may be noticeable at rest or at night, though experiences vary from person to person.
Arterial ulcers are different from venous ulcers, which relate to blood returning from the legs to the heart, and from pressure injuries. Telling them apart takes a professional evaluation, because the cause shapes which kinds of care are considered safe and appropriate.
How it’s traditionally been approached
Traditionally, arterial ulcer care begins with finding out why blood flow is reduced. Clinicians commonly look at the history, examine the leg and foot, and may use circulation tests to assess blood supply. Vascular specialists are often involved because the underlying circulation problem is central to healing.
Wound care itself has often included cleaning the wound, protecting it with dressings chosen by the clinician, and working to manage pain and lower the risk of infection. Some approaches used for other wounds, such as strong compression, may not be suitable when arterial flow is limited, which is why a proper evaluation matters.
Depending on the findings, care teams may also consider procedures that aim to improve blood flow, along with attention to overall health factors such as diabetes, smoking and blood pressure. Advanced options such as negative pressure wound therapy, skin substitutes or hyperbaric oxygen therapy are sometimes discussed, but only a licensed clinician can decide whether any of them fit a particular situation.
How the right wound care specialist may help
The right wound care specialist may help by looking at the whole picture: the wound, your circulation, your health history and your daily routine. A first visit often includes questions about when the wound began, your pain, past vascular problems and current medications. The clinician may examine your pulses, skin and foot, and may order circulation testing or refer you to a vascular specialist.
A specialist may also measure and document the wound so changes can be tracked over time, and explain what they see in plain language. Follow-up visits are common, since arterial wounds are watched closely for changes. A good provider should be willing to explain the reasoning behind their recommendations.
Questions worth asking include: What is causing my wound? How would you describe its stage or severity? What treatment options exist, and what are the pros and cons of each? How long might healing take, and what could slow it? What will my insurance cover? Are any products or therapies I hear about, including skin substitutes or amniotic grafts, appropriate for me, and what is their FDA status?

The whole-person view
Living with a slow-healing wound can be stressful. Pain, disrupted sleep, worry about mobility and frequent appointments can weigh on mood, and stress and low mood can in turn affect sleep, appetite and daily habits that support overall health. Body, mind and stress influence one another, so caring for the whole person can be a meaningful part of the picture.
Some people find body-based support, such as the approaches listed through Somatic Experiences, helpful for managing the tension that often comes with chronic pain. Others value talking with a licensed counselor through Therapists.plus about coping with the emotional side of a long recovery. These are complements to medical care, not replacements for it.

Keep in mind
- This page is educational only and is not medical advice; only a licensed clinician can evaluate your wound and decide what is appropriate.
- Seek medical care promptly for spreading redness, red streaking, increasing warmth or pain, pus, foul odor, fever or chills, or a wound that is quickly getting worse.
- Call 911 or go to the ER for heavy bleeding, exposed bone or tendon, signs of sepsis, or a deep or severely contaminated wound. Skin that turns cold, pale or blue with sudden severe pain also needs urgent attention.
- If you are in emotional crisis, call or text the 988 Lifeline. Coverage and regulatory status vary by product and payer, so ask your provider and insurer.

Frequently asked questions
What is the best arterial ulcer treatment?
There is no single best arterial ulcer treatment, because the right approach depends on the cause, your circulation and your overall health. Care commonly focuses on assessing blood flow and protecting the wound, often with a vascular specialist involved. A licensed clinician can explain which options may fit your situation.
Can an arterial ulcer heal on its own?
Arterial ulcers often struggle to heal without addressing the underlying blood flow problem. Because the tissue is not getting enough oxygen, waiting can allow the wound to worsen or become infected. A professional evaluation is the safest way to understand your wound.
How is an arterial ulcer different from a venous ulcer?
An arterial ulcer is caused by reduced blood flow into the leg or foot, while a venous ulcer relates to blood having trouble returning toward the heart. Arterial ulcers often look punched-out and occur on toes or heels, while venous ulcers tend to appear around the lower leg or ankle. A clinician should confirm which type you have, since care differs.
Is compression safe for an arterial ulcer?
Compression is not automatically safe for an arterial ulcer, because it may further limit blood flow when arteries are already narrowed. Clinicians typically check circulation before recommending it. Always ask a licensed provider before using compression on any leg wound.
What kind of doctor treats arterial ulcers?
Wound care specialists and vascular specialists commonly work together on arterial ulcers. Podiatrists, primary care clinicians and other providers may also be involved. You can use a directory like Providers.plus to find licensed providers.
When should I see someone about an arterial ulcer?
See a clinician as soon as you notice a sore on your foot or leg that is not healing, especially if you have diabetes or known circulation problems. Seek care promptly for signs of infection such as spreading redness, pus, odor, fever or chills. Call 911 or go to the ER for heavy bleeding, exposed bone or tendon, or signs of sepsis.
