Leg pain is a common complaint that affects millions of Americans, but many people don’t realize that their discomfort could be related to vascular problems. When blood vessels in your legs aren’t functioning properly, it can lead to various types of pain, swelling, and other uncomfortable symptoms.

At The Vein Institute, we treat leg pain as a symptom of vein conditions every day. Understanding the vascular causes of leg pain leads to early detection and treatment, which can prevent serious complications and improve your quality of life. Here are seven vascular conditions that could be behind your leg pain.

Understanding When Leg Pain Signals a Vascular Problem

1. Peripheral Artery Disease (PAD)

Key Statistic: Approximately 6.5 million people in the United States over age 40 have peripheral artery disease. 

Peripheral Artery Disease occurs when arteries that supply blood to your legs become narrowed or blocked due to plaque buildup. This condition affects nearly 200 million people worldwide and is considered a cardiovascular disease equivalent, carrying high risks for heart attacks and strokes.

Symptoms include: Leg pain during walking (claudication) that stops with rest, numbness, coldness in the lower leg or foot, and slow-healing wounds on the feet or legs.

2. Chronic Venous Insufficiency (CVI)

Key Statistic: Each year, approximately 150,000 new patients are diagnosed with chronic venous insufficiency, and nearly $500 million is spent on their care.

Chronic Venous Insufficiency is a condition in which venous blood flow is impaired, leading to venous hypertension. This prevalent disease process significantly impacts quality of life and work productivity. The condition typically results from incompetent venous valves that fail to prevent blood from flowing backward and pooling in the legs.

Symptoms include: Dependent pitting edema, leg discomfort, fatigue, itching, varicose veins, pain that improves with leg elevation, and cramping sensations.

3. Varicose Veins

Key Statistic: Approximately 23% of US adults have varicose veins. When spider veins and reticular veins are included, the prevalence increases to 80% of men and 85% of women.

Varicose veins affect 22 million women and 11 million men between the ages of 40 and 80 in the United States. While many people seek treatment for cosmetic reasons, varicose veins can cause significant symptoms. The Edinburgh Vein Study found that 40% of men and 32% of women had trunk varices, with the condition becoming more common with age.

Symptoms include: Heavy, achy feeling in legs, itching or burning sensation, muscle cramps, swelling in legs and ankles, and worsening symptoms with prolonged standing.

4. Deep Vein Thrombosis (DVT)

Key Statistic: As many as 900,000 people could be affected by venous thromboembolism each year in the United States, with an estimated 60,000-100,000 Americans dying from VTE annually.

Deep vein thrombosis involves the formation of blood clots in deep veins, most commonly in the legs. It’s the third most common cause of death from cardiovascular disease after heart attacks and strokes. Lower-extremity DVT has a prevalence of about 1 case per 1000 population and is the underlying source of 90% of acute pulmonary embolisms.

Symptoms include: Swelling in one leg, pain or tenderness, warmth in the affected area, and red or discolored skin. However, some DVTs have no symptoms.

5. Post-Thrombotic Syndrome (PTS)

Key Statistic: Post-thrombotic syndrome develops in 20% to 50% of patients after DVT, with severe PTS, including venous ulcers, developing in 5% to 10% of cases.

Post-Thrombotic Syndrome is a chronic complication of deep vein thrombosis that can develop even with appropriate anticoagulation treatment. Approximately 330,000 people in the United States have this condition, which can significantly reduce quality of life and work productivity.

Symptoms include: Chronic leg pain, swelling, heaviness, skin discoloration, and, in severe cases, venous ulcers. Among DVT patients, one-third to one-half will have long-term complications such as swelling, pain, and scaling in the affected limb.

6. Superficial Thrombophlebitis

Key Statistic: Superficial venous thrombosis has an estimated incidence of 0.3-0.6 events per 1000 person-years in young people and 0.7-1.5 events per 1000 person-years in older patients.

Superficial thrombophlebitis involves blood clot formation in veins close to the skin surface, often accompanied by inflammation. Studies show that 24.6% of patients with superficial venous thrombosis also have concomitant deep vein thrombosis, underscoring the importance of proper evaluation.

Symptoms include: Warmth, tenderness, pain, redness, and swelling along the vein, and a visible red, hard cord under the skin that’s tender to touch.

7. May-Thurner Syndrome

Key Statistic: Iliac vein compression occurs in about 1 in 5 people, though many don’t have symptoms. May-Thurner syndrome is more common in women and adults aged 20-50.

May-Thurner Syndrome occurs when the right iliac artery compresses the left iliac vein, potentially causing venous insufficiency and increasing the risk of deep vein thrombosis. While the condition may be present in up to 22% of the population based on cadaveric studies, many people remain asymptomatic unless complications develop.

Symptoms include: Left leg swelling, feelings of heaviness, skin discoloration, varicose veins, and, in some cases, chronic pelvic pain. The condition can also lead to pelvic congestion syndrome in women.

Don’t Ignore Persistent Leg Pain

If you’re experiencing chronic leg pain, swelling, heaviness, or other concerning symptoms, it’s important to get a proper vascular evaluation. Many vascular conditions are highly treatable when caught early, but can lead to serious complications if left undiagnosed.

The Vein Institute offers comprehensive vascular screenings to help identify the cause of your leg pain and develop an appropriate treatment plan. Our experienced team uses advanced diagnostic tools to assess your vascular health and provide personalized care.
