Why Won't My Leg Wound Heal? Venous Disease May Be to Blame

If you have a sore on your lower leg that won't close, or a leg wound that isn't healing the way it should, the answer may not be in the wound itself. It may be in your veins.

The wound is not the disease. It is a symptom of underlying vein disease, most often a progressive condition called chronic venous insufficiency, or CVI. According to the NIH/NLM, CVI is responsible for 70 to 90 percent of all chronic lower-leg wounds.

Between 500,000 and 2 million Americans are living with a venous leg ulcer at any given time, and most receive wound care without the underlying vascular cause ever being identified or treated. Some heal, but a troubling number don't, or they heal and then return with the same wound in the same spot months later.

That cycle is not a failure of care. It's the result of treating the wound without addressing the underlying cause: chronic venous insufficiency.

To learn more about the link between leg wounds and vein disease, we consulted Sanjiv Lakhanpal, MD, FACS, Founder, President, and CEO of Center for Vein Restoration (CVR), the nation's largest physician-led vein practice with 130+ locations across 23 states. As a cardiovascular and thoracic surgeon, Dr. Lakhanpal witnessed firsthand the pain, swelling, skin changes, and ulceration caused by CVI, as well as the harm of leaving it undiagnosed, which often traps patients in a cycle of leg wounds that won't heal. 

That experience drove him to build CVR around a single principle: treat the cause, not just the wound.

What Is Venous Disease, and Why Does It Cause Wounds?

Your leg veins have a tough job. Every time you stand up, they push blood upward against gravity, back toward your heart. Small valves inside the veins open and close to keep that blood moving in the right direction.

When those valves stop working properly due to age, genetics, pregnancy, a history of blood clots, or years of standing on the job, blood pools in the lower leg. That pooling creates pressure. Over time, the pressure damages the tiny blood vessels near the skin. Fluid leaks into the tissue. The skin discolors, hardens, and eventually breaks down into an open wound.

Cleveland Clinic describes this progression clearly: when venous pressure builds high enough, the smallest blood vessels in the leg can burst. The surrounding skin turns reddish-brown and becomes fragile enough that even a small bump or scratch can open a wound that won't close easily on its own.

According to the NIH/NLM, chronic venous insufficiency affects roughly 1 in 20 adults, with approximately 150,000 new patients diagnosed in the U.S. each year.

You may be at higher risk for developing vein disease if you:

• Stand or sit for long periods at work (think nurses, teachers, factory workers, retail staff)
• Have a parent or grandparent who had varicose veins
• Have had a blood clot (DVT) in your leg
• Are over 50
• Have been pregnant one or more times
• Are overweight
• Have varicose veins that cause pain, swelling, or heaviness

As Mayo Clinic Health System notes, varicose veins are far more than a cosmetic issue. At their worst, they signal the early stages of progressive venous disease that can ultimately lead to poor wound healing, ulcers, and serious complications if left untreated.

Why Wound Care Alone Is Often Not Enough

Wound care matters. Cleaning a wound, keeping it moist, and applying compression bandages are all important steps. They help the wound heal.

But compression therapy cannot fix faulty valves in veins. It reduces pressure on the leg while you're wearing it, but once the bandage or stocking comes off, the underlying problem remains. The blood still pools. The pressure still builds. The wound still has the same conditions as it had before.

Cleveland Clinic explains that treating the source of venous reflux, the backflow of blood through damaged valves, changes the long-term outcome. Wound management treats the surface. Venous treatment addresses the cause.

The research on this is detailed and definitive and has been firmly established for more than two decades.

Can Treating Your Veins Help Heal a Leg Ulcer? What Research Shows

The ESCHAR Trial

In a landmark study of 500 patients published in The Lancet and followed up in the BMJ, researchers compared two groups: patients treated with compression therapy alone, and those treated with compression plus a procedure to correct the faulty veins.

At 24 weeks, both groups healed at similar rates. That's an important finding on its own because it means treating the veins does not slow down or interfere with wound healing.

What was dramatically different was what happened afterward. At four years, the recurrence rate for patients who received only compression was 56 percent. For patients who had their faulty veins corrected, the recurrence rate dropped to 31 percent, nearly half. For patients with the most common and treatable pattern of venous disease (reflux limited to the superficial veins), the numbers were even clearer: 51 percent recurrence with compression alone versus 27 percent with venous correction.

The study's conclusion was straightforward: fixing the underlying venous problem, not just the wound, is what keeps the wound from coming back.

The EVRA Trial

Fourteen years later, a major randomized trial published in The New England Journal of Medicine answered a second critical question: does the timing of venous treatment matter?

The answer was yes, and it matters more than many expected.

Researchers enrolled 450 patients with active venous leg ulcers and divided them into two groups. One group received early endovenous ablation, a minimally invasive vein procedure, within two weeks of diagnosis alongside standard wound care. The other group received compression therapy first, with vein treatment deferred until after the wound closed.

Median healing time in the early treatment group: 56 days. In the deferred group: 82 days. The healing rate at 24 weeks was 85.6 percent with early treatment, compared with 76.3 percent in the group that waited. Patients who received early venous treatment also spent more time wound-free in the following year: 306 days compared to 278 days.

The study's authors made a point that stands on its own: worldwide, many patients with venous leg ulcers never receive an assessment or treatment for the venous disease causing those ulcers, partly because vein treatment is wrongly assumed to be cosmetic or elective. The EVRA trial made clear this assumption is both clinically and economically indefensible.

The bottom line from both trials: treat the veins early, and wounds heal faster, recur less often, and cost the healthcare system significantly less.

CVR's board-certified vein experts use comprehensive duplex ultrasound to determine whether faulty vein valves are behind your wound and treat the cause directly. Find a CVR location near you or call 240-249-8250 to schedule your consultation, or click on the link below ⬇️

If You Have a Wound Right Now, Don't Wait for It to Close

One of the most important things the EVRA trial established is that you do not have to wait for your wound to heal before having your veins evaluated and treated. In fact, waiting costs time.

If you have an open wound on your lower leg, especially one that has persisted for weeks without significant improvement, ask your doctor for a referral to a venous specialist. The standard diagnostic test is a duplex ultrasound, a simple, painless imaging scan that maps blood flow in your leg veins and identifies faulty valves and their locations. It takes about 30 minutes and requires no preparation.

According to NIH/NLM data, between 40 and 50 percent of venous leg ulcers are still open after 6 to 12 months of standard wound management alone. Ten percent remain open for up to five years. The annual Medicare cost of caring for a single patient with a venous leg ulcer is $18,986. Those numbers reflect what happens when the wound is treated, and the cause is not.

A CVR vein specialist can evaluate your venous anatomy and identify the cause of your wound, often in a single visit. Schedule your consultation today or call 240-249-8250 for more information.

If You Don't Have a Wound Yet, Now Is the Right Time to Act

Venous disease follows a predictable path. It starts silently. You might notice achy or heavy legs at the end of the day, mild swelling around the ankle, or small spider veins on the calf. These early signs are easy to dismiss.

Over time, the signs become harder to ignore: prominent varicose veins, persistent swelling, a brownish discoloration on the skin above the ankle, and skin that feels thickened or leathery to the touch. These skin changes, known as lipodermatosclerosis, a condition where the skin and underlying tissue harden and tighten, are a warning that the tissue is under chronic venous stress and is approaching the point of breakdown.

Ulceration is not inevitable. It is the end stage of a process that can be interrupted at any point along the way. The earlier venous disease is identified and treated, the less likely it is to progress to a wound.

If you recognize any of these warning signs, a consultation with a CVR vein specialist is the right next step. Find a location near you or call 240-249-8250 today to speak with a patient services representative. Don't wait for a painful wound to tell you there's a problem.

How CVR Treats the Vein Disease Behind Your Leg Wound

Center for Vein Restoration is the nation's largest physician-led vein practice, with 130+ locations in 23 states. Our board-certified physicians specialize in the comprehensive evaluation and treatment of venous disease, ranging from early-stage varicose veins to complex venous insufficiency that can lead to chronic wounds.

Our modern vein treatment uses minimally invasive outpatient procedures, most commonly endovenous thermal ablation (laser or radiofrequency energy delivered through a thin catheter) or ultrasound-guided foam sclerotherapy to close off faulty veins from the inside. Cleveland Clinic describes endovenous thermal ablation as a nonsurgical procedure performed under local anesthesia, typically in under an hour, with minimal recovery time and a much lower complication rate than traditional vein stripping surgery. Most patients walk out of the office the same day. These procedures do not remove your veins. They seal the faulty ones so that blood reroutes through healthy vessels. The treated veins fade over time.

Every patient evaluation at CVR begins with a comprehensive duplex ultrasound to map venous anatomy and precisely locate faulty valves. From there, our physicians discuss minimally invasive treatment options tailored to your specific anatomy and goals. For patients with open wounds, these procedures can be scheduled alongside wound care and do not require you to pause your existing treatment plan.

We work alongside wound care teams, primary care physicians, and hospital systems to ensure patients with lower-extremity wounds receive the vascular evaluation that the evidence demands, not just wound dressing changes.

With 130+ locations across 23 states, a CVR vein specialist is closer than you think. Find a location near you or call 240-249-8250. 

Frequently Asked Questions

1. Why do leg wounds caused by venous disease keep coming back even after they heal? When a wound closes, the underlying vein problem, faulty valves that allow blood to pool in the leg, is still there. That continued pressure on the skin and tissue creates the exact same conditions that caused the first wound, which is why recurrence rates can reach 50 percent or higher when only the wound is treated. Correcting the venous reflux that drives the pressure is what breaks the cycle.
2. What is a duplex ultrasound, and do I need one? A duplex ultrasound is a painless, non-invasive imaging test that uses sound waves to show how blood is moving through the veins in your leg. If you have a lower leg wound or visible signs of venous disease such as varicose veins, swelling, or skin discoloration, a duplex ultrasound is the first step in determining whether faulty vein valves are present and where.
3. Can my veins be treated while my wound is still open? Yes. The EVRA trial, published in The New England Journal of Medicine, found that patients who received venous treatment while their wound was still open healed significantly faster than those who waited. Venous procedures are outpatient treatments that can run alongside wound care without disrupting it.
4. What does venous disease look like before a wound develops? Early venous disease often presents as leg heaviness or achiness at the end of the day, mild ankle swelling that improves with elevation, visible spider veins or varicose veins, and occasional leg cramping. As the disease progresses, skin around the ankle may darken, itch, or feel hard and leathery. These are warning signs that venous pressure is building, and that the window to prevent a wound is still open.
5. Is vein treatment a major procedure? At CVR, venous treatment is minimally invasive and performed in an outpatient setting under local anesthesia. Procedures usually take less than an hour, require no general anesthesia, and allow most patients to return to normal activities the same day or within a few days.
6. How do I know if my wound is venous in origin? Venous leg ulcers typically appear on the lower leg between the ankle and the calf, particularly near the inner ankle. They are often shallow, irregular in shape, and accompanied by surrounding skin that is discolored, swollen, or thickened. A duplex ultrasound performed by a CVR venous specialist is the definitive test to confirm whether vein disease is driving the wound.
7. Is vein treatment covered by insurance? When venous disease causes clinical symptoms, including leg wounds, significant swelling, skin changes, or pain, treatment is generally considered medically necessary rather than cosmetic and is typically covered by Medicare and most commercial insurance plans. A CVR physician can review your specific situation and insurance coverage during your consultation.
8. What if I have varicose veins but no wound yet? Should I still see a specialist? Yes. Varicose veins are not purely cosmetic. They are visible evidence that venous valves are not working properly, and they can progress to more serious disease over time. Seeing a venous specialist early allows you to understand your current venous health, monitor for progression, and pursue treatment before a wound develops.
