Chronic Venous Insufficiency: Why Your Legs Ache, Swell, and Feel Heavy
Aching, heavy, swollen legs at the end of the day are not just a normal part of getting older — they're often a sign of chronic venous insufficiency, a common and treatable circulation problem. Chronic venous disease affects more than 25 million adults in the United States, yet it frequently goes undiagnosed or is dismissed as cosmetic.
Cardentey Vascular Care treats venous disease as what it is: a medical condition that can progress if ignored, and one that responds well to proper diagnosis and modern, minimally invasive treatment.
What is chronic venous insufficiency?
Chronic venous insufficiency (CVI) is a condition in which the veins in your legs can't return blood to the heart efficiently. Healthy leg veins have one-way valves that keep blood moving upward against gravity. When those valves weaken or fail, blood pools in the lower legs — a problem called venous reflux. Over time, the pressure from that pooling causes the symptoms and skin changes of CVI.
What are the symptoms of venous insufficiency?
The most common symptoms are leg aching, heaviness, and swelling that worsen with standing and improve with elevation. Many people notice their legs feel best in the morning and worst by evening. Other signs include:
- Aching, throbbing, or a feeling of heaviness or fatigue in the legs
- Swelling in the ankles and lower legs, especially after standing
- Itching or restless legs
- Visible varicose veins or spider veins
- Skin changes near the ankle — darkening, dryness, or a leathery texture
- In advanced cases, open sores (venous ulcers) that are slow to heal
Is venous insufficiency dangerous, or just a cosmetic issue?
Venous insufficiency is a medical condition, not merely a cosmetic one. While it often begins with visible veins or mild aching, it is progressive: untreated, it can lead to chronic swelling, skin damage, and venous leg ulcers that are difficult to heal. Treating it early relieves symptoms and helps prevent these later complications. This is an important distinction — the visible veins are a window into an underlying circulation problem, not just a surface blemish.
What causes CVI, and who is at risk?
CVI develops when the vein valves fail and pressure builds in the leg veins. Your risk is higher if you:
- Have a family history of varicose veins or venous disease
- Are female, have been pregnant, or have had multiple pregnancies
- Stand or sit for long periods (common in many jobs)
- Are older, overweight, or less physically active
- Have a history of blood clots (deep vein thrombosis) in the legs
How is chronic venous insufficiency diagnosed?
CVI is diagnosed with a painless ultrasound called a venous duplex scan, which shows how blood is flowing through your leg veins and pinpoints exactly which valves are leaking. This step matters more than many people realize. A proper ultrasound is what separates real diagnosis from guesswork — it maps the problem so treatment targets the actual source of reflux, rather than just the veins you can see on the surface.
How is venous insufficiency treated?
Treatment follows an evidence-based ladder, starting conservative and escalating only as needed. Most patients begin with measures that are simple and effective.
Conservative care (the foundation):
- Compression stockings to support the veins and reduce swelling
- Leg elevation, regular walking, and weight management
Minimally invasive procedures (when symptoms persist):
- Endovenous ablation — closing the faulty vein from the inside using heat (radiofrequency or laser), so blood reroutes to healthy veins. This is the modern standard and has largely replaced old-fashioned vein stripping.
- VenaSeal — a non-thermal option that seals the vein closed with a medical adhesive, often with minimal discomfort and no need for numbing injections along the vein.
- Sclerotherapy — an injection that closes smaller veins.
- Phlebectomy — removal of larger surface veins through tiny punctures.
These are office-based or outpatient procedures, most patients walk out the same day, and when treatment is for medical symptoms, it is often covered by insurance.
When should I see a vascular specialist for leg swelling or vein problems?
You should see a vascular specialist if you have ongoing leg aching, heaviness, or swelling, visible varicose veins with symptoms, or any skin changes or sores near the ankle. A vascular evaluation can confirm whether venous insufficiency is the cause and identify the most effective treatment.
FAQ
Frequently asked questions
Venous insufficiency is the underlying problem — failing vein valves that let blood pool in the legs. Varicose veins are one visible result of that problem. You can have venous insufficiency causing aching and swelling even without prominent varicose veins, which is why an ultrasound is the only way to know what’s really happening.
Usually not. Venous insufficiency is progressive, meaning it tends to worsen gradually over time rather than resolve. The good news is that it's very treatable — conservative measures help many people, and minimally invasive procedures can address the underlying reflux when symptoms persist.
When treatment is for medical symptoms — aching, swelling, skin changes, or ulcers caused by venous insufficiency — it is often covered by insurance, typically after a documented trial of conservative measures like compression. Purely cosmetic treatment of spider veins is generally not covered. An evaluation can clarify where your situation falls.
Modern vein treatments are minimally invasive and done in the office or outpatient setting. Most people return to normal activities quickly, often the same day, with little downtime. These procedures have largely replaced the older, more invasive vein-stripping surgery.
