We all get minor cuts and scrapes on our feet from time to time. Maybe you stepped on something sharp, or perhaps a new pair of shoes caused a blister. For most people, a bandage and a few days of patience are all it takes for the skin to heal. But what happens when that small wound doesn’t go away? What if, weeks or even months later, it’s still there—or getting worse?
A wound that refuses to heal is not just a stubborn injury; it is a loud warning signal from your body. In many cases, it is a primary indicator of severe Peripheral Arterial Disease (PAD), a progressive circulatory condition that can threaten your limb and your life.
At Fox Vein and Vascular in Manhattan, we see many patients who have been treating a wound with creams and bandages for months, unaware that the real problem lies deep within their arteries. Dr. David Fox and our team of vascular experts want you to know the signs of severe PAD so you can seek the urgent care necessary to save your limb.
What Is Severe PAD?
Peripheral Arterial Disease (PAD) occurs when the arteries supplying blood to your legs become narrowed or blocked by plaque buildup (atherosclerosis). In its early stages, PAD might cause cramping in your legs when you walk—a symptom known as claudication.
However, if left untreated, the disease progresses. The arteries become so blocked that they cannot deliver enough oxygen-rich blood to the tissues even when you are resting. This advanced stage is often called Critical Limb Ischemia (CLI).
When you have severe PAD, your skin and muscles are essentially suffocating. They lack the nutrients needed to maintain healthy tissue, let alone repair an injury. This is why a minor scratch can turn into a dangerous, chronic ulcer.
Recognizing the Warning Signs
How do you know if a wound is just a wound, or if it’s a symptom of severe vascular disease? There are several distinct characteristics of arterial ulcers and advanced PAD symptoms you should watch for:
1. The Wound Won’t Heal
The most obvious sign is time. A healthy body should start healing a minor skin injury within a few days. If you have a non-healing wound/ulcer of toe, leg, foot that has persisted for more than two weeks despite proper care, it is a major red flag.
2. “Punched-Out” Appearance
Arterial ulcers often look different from other types of sores. They frequently appear on the toes, heels, or ankles (pressure points). They tend to be deep, with well-defined borders that look like they were punched out of the skin. The base of the wound is often pale, gray, or black, rather than a healthy red, because there is no blood flow.
3. Pain at Night (Rest Pain)
Severe PAD often causes intense pain in the feet or toes, particularly when you are lying in bed. You might find yourself hanging your foot over the edge of the bed or sleeping in a chair to get relief. This is because gravity helps pull what little blood is available down to your feet. If you have a foot wound and this type of pain, your condition is critical.
4. Cold, Pale, or Discolored Skin
If you touch the foot with the wound, it may feel noticeably colder than your other foot. The skin might look shiny, thin, and hairless. When you elevate your leg, the foot may turn pale white; when you lower it, it may turn a deep red or purple (rubor).
The Risks of Delayed Treatment
Ignoring a non-healing wound is dangerous. Because the tissue is already compromised by poor blood flow, infection can set in rapidly. Without a strong blood supply, your body cannot send white blood cells to fight the bacteria or antibiotics to the site of infection.
This can lead to a cascading series of complications:
- Spreading Infection: The infection can move deep into the soft tissues and even infect the bone (osteomyelitis).
- Gangrene: Without oxygen, the tissue eventually dies and turns black. This is gangrene, a condition that is irreversible for the affected tissue.
- Amputation: Once gangrene sets in or an infection becomes uncontrollable, amputation prevention becomes much more difficult. In severe cases, removing the toe, foot, or leg may be the only way to save the patient’s life.
The Role of a Vascular Specialist
If you have a non-healing foot wound, seeing a wound care specialist or a podiatrist is an important step. However, if the underlying cause is blocked arteries, wound care alone will fail. You cannot heal a wound on a limb that is starving for blood.
This is why a vascular specialist is an essential part of the care team. Dr. Fox specializes in identifying and treating the root cause of the ulcer: the lack of circulation.
Diagnosing the Flow
At our state-of-the-art vascular lab in Manhattan, we use non-invasive tests like the Ankle-Brachial Index (ABI) and Duplex Ultrasound to map your arteries. We can tell you exactly where the blockage is and how severe it is.
Restoring the Flow
The goal of PAD treatment for severe cases is revascularization—restoring the blood flow. Dr. Fox utilizes advanced, minimally invasive techniques to open blocked arteries without major surgery.
- Angioplasty: Inflating a small balloon to widen the artery.
- Stenting: Placing a mesh tube to keep the vessel open.
- Atherectomy: Removing plaque from the artery walls.
These procedures are performed in an outpatient setting and can often restore flow immediately. Once the “pipes” are open and blood reaches the foot, the wound finally has the oxygen and nutrients it needs to heal.
Don’t Wait Until It’s Too Late
A foot wound is not just a nuisance; it is a countdown. The longer it remains unhealed, the higher the risk of infection and limb loss.
If you or a loved one has a sore on the leg or foot that isn’t healing, especially if you have risk factors like diabetes, smoking history, or high blood pressure, do not wait. Early intervention by a vascular surgeon is the most effective way to save your limb and your mobility.
At Fox Vein and Vascular, we serve patients from the 5 Boroughs, Nassau, Suffolk, South Western CT, and North East NJ. We are dedicated to Dr. Fox’s mission of limb preservation through expert vascular care.
