Compression Stockings for Venous Insufficiency

How Compression Stockings Support Venous Insufficiency, Tired Legs, and DVT Prevention

If your legs feel heavy, achy, tired, or swollen at the end of the day, you’re not alone. These symptoms are common among people who spend long hours sitting or standing, and they can also signal an underlying vein condition called chronic venous insufficiency (CVI).

At The Compression Closet, we believe that choosing the right compression garment starts with understanding your needs.

Understanding Venous Insufficiency and Healthy Circulation

To understand why compression stockings help, it is useful to know how blood circulates through your legs.

Your veins carry blood from your lower limbs back toward your heart. Because blood must travel upward against gravity, veins contain small one-way valves that help prevent blood from flowing backward. The calf muscles also act as a pump, helping move blood upward when you walk.

When vein valves become damaged or stop functioning properly, blood can flow backward and pool in the lower legs. This is known as venous reflux and can contribute to chronic venous insufficiency.

Common symptoms of chronic venous insufficiency

Aching, heaviness, or fatigue in the legs
Swelling around the ankles and lower legs
Varicose veins
Itching or irritation of the skin
Brownish skin discoloration, particularly around the ankles
Thickened or hardened skin in more advanced disease
Venous leg ulcers that heal slowly or recur

Symptoms may worsen after prolonged sitting or standing and often improve when the legs are elevated.

Chronic venous disease can range from mild symptoms to more advanced skin changes and ulcers. The 2025 Society for Cardiovascular Angiography & Interventions (SCAI) clinical practice guidelines address compression therapy and other treatment options, including procedures that target abnormal veins.

How Do Compression Stockings Work?

Graduated compression stockings apply the greatest pressure at the ankle, with pressure gradually decreasing up the leg.

This graduated pressure helps support blood return toward the heart. Compression also helps limit fluid accumulation in surrounding tissues, which can reduce swelling and discomfort.

Compression stockings may help:

Reduce lower-leg and ankle swelling.
Relieve sensations of aching, heaviness, and tiredness.
Support venous circulation during daily activities.
Manage symptoms associated with varicose veins and chronic venous disease.
Support the treatment of venous leg ulcers when used as part of appropriate wound care.

Compression does not repair damaged vein valves or eliminate the underlying cause of venous insufficiency. However, it can be an important part of ongoing symptom management.

What does the research say?

The 2025 SCAI guidelines suggest compression therapy for people with symptomatic varicose veins. They also strongly recommend compression therapy for people with venous ulcers, based on moderate-certainty evidence.

In the guideline’s review, compression therapy was associated with a higher rate of ulcer healing compared with no compression. The panel also recognized that some people may benefit from vein procedures, depending on their condition and preferences.

This distinction matters: compression is an established part of venous disease management, but it is not the only treatment available.

Why Wear Compression Stockings for Tired, Achy Legs?

You don’t necessarily need a diagnosis of venous insufficiency to experience tired, uncomfortable legs.

People who spend much of their day standing—such as nurses, teachers, retail workers, and hair stylists—may notice leg fatigue and swelling by evening. Prolonged sitting can also contribute to fluid accumulation and reduced calf-muscle activity.

For people with venous circulation symptoms, compression stockings may provide meaningful relief.

Potential benefits of compression stockings

1. Help reduce swelling

Compression helps limit fluid accumulation in the lower legs and ankles. This can be especially helpful for people experiencing dependent swelling associated with venous disease.

Our Juzo Dynamic collection offers options for people who need different garment lengths:

2. Relieve aching and heaviness

Compression may help reduce discomfort associated with symptomatic venous disease. Relief varies from person to person and depends on the cause of the symptoms.

Mediven Plus offers a range of compression options and sizes.

3. Support comfort during long workdays

For people who spend many hours on their feet, properly selected compression socks may make daily activities more comfortable.

Therafirm Core-Spun Compression Socks offer a variety of styles and colors.

4. Help manage symptoms associated with varicose veins

Compression can help reduce aching, heaviness, and swelling associated with varicose veins. It does not remove existing varicose veins or permanently correct the underlying venous reflux.

The response to compression varies, and some people may be candidates for additional treatments.

Choosing Compression Stockings for Venous Insufficiency

One of the most common questions we hear is: “What compression level do I need?”

Compression garments are labeled according to the pressure they provide, measured in millimeters of mercury (mmHg). The appropriate pressure depends on your symptoms, diagnosis, circulation, skin condition, and ability to wear and apply the garment.

Common compression levels


8–15 mmHg	Light support; selected for mild symptoms
15–20 mmHg	Mild compression for some people with tired, aching legs or mild swelling
20–30 mmHg	Frequently used for symptomatic venous disease, varicose veins, and selected cases of edema
30–40 mmHg	Higher compression that may be prescribed for more advanced venous disease or certain venous ulcers

These are general examples, not a prescription or universal treatment guide. Compression classifications and product labeling can vary, and what works for one person may not work for another.

Higher compression isn’t automatically better. The right choice safely addresses your needs and is one you can wear consistently. I suggest the lowest compression that effectively addresses your condition.

Knee-high, thigh-high, or waist-high?

Knee-high compression stockings

Often a practical choice when symptoms and swelling primarily affect the lower legs and ankles.

Compression Stockings and Deep Vein Thrombosis (DVT)

Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, usually in the leg. A clot can sometimes travel to the lungs, causing a pulmonary embolism (PE), which can be life-threatening.

DVT and chronic venous insufficiency are different conditions. Although both involve the veins, they should not be treated as interchangeable diagnoses.

Can compression stockings prevent DVT?

Compression stockings have specific uses in blood clot prevention, but they are not a substitute for medical evaluation or prescribed anticoagulant medication when those treatments are indicated.

Compression may be used as part of a hospital or postoperative prevention plan, depending on the patient’s condition and risk of bleeding or clotting. The treating medical team should determine the type of compression and whether it is appropriate.

Compression stockings during long-distance travel

Long periods of sitting during air, car, bus, or train travel can increase the risk of blood clots, particularly in people with additional risk factors.

The CDC’s 2026 travel health guidance notes that graduated compression stockings can reduce asymptomatic DVT in some long-distance travelers. Recommendations differ according to individual risk.

For travelers who may be at increased risk, preventive measures can include:

Moving around periodically when it is safe and practical.
Exercising the calf muscles and moving the ankles while seated.
Considering properly fitted graduated compression stockings after discussing individual risk with a healthcare professional.
Asking a healthcare professional whether additional preventive measures are appropriate.

People with a history of blood clots, recent surgery, active cancer, pregnancy or postpartum status, or other significant risk factors should seek individualized advice before long-distance travel.

Compression stockings are not routinely necessary for every traveler, and you should not start clot-prevention medication without medical guidance.

When to Seek Medical Attention

Compression stockings support leg health, but they should not be used to dismiss new or unexplained symptoms.

Possible signs of DVT

Seek prompt medical evaluation if you develop new, unexplained swelling, pain, tenderness, warmth, or discoloration in one leg, especially if these symptoms occur together.

Possible signs of pulmonary embolism

Seek emergency medical care.

Sudden difficulty breathing, chest pain (especially pain that worsens with breathing), coughing up blood, fainting, or severe lightheadedness can be signs of a pulmonary embolism.

Call 911 if you experience these symptoms.

The CDC provides further information about recognizing blood clots and seeking appropriate care.

Tips for Wearing Compression Stockings

The right compression stocking should provide appropriate support without causing unnecessary discomfort. Correct sizing, application, and care are important for both comfort and effectiveness.

1. Get professionally fitted

Compression sizing isn’t the same as ordinary sock sizing. Measurements may include the ankle, calf, and leg length, and you should take them according to the manufacturer’s instructions.

2. Put your stockings on in the morning

For many people with venous swelling, applying stockings in the morning—before significant swelling develops—makes them easier to put on and helps maintain support throughout the day.

Follow your clinician’s instructions about when to wear and remove your garments.

Learn how to put on compression stockings.

3. Make sure they fit correctly

A properly fitted garment should lie smoothly against the skin without bunching, rolling, or creating painful pressure points.

Avoid folding or rolling the top band, as this can create localized pressure.

If you experience new numbness, tingling, pain, skin discoloration, or cold toes, remove the garment if safe to do so and seek advice from your healthcare professional.

4. Wash and care for your garments

Follow the specific manufacturer’s washing and drying instructions. Gentle laundering and avoiding excessive heat can help preserve elastic fibers.

Read our guide to caring for compression stockings.

5. Replace worn-out stockings

Compression garments gradually lose elasticity with repeated wear and washing. Replacement timing varies by garment, use, care, and manufacturer recommendations.

Many people replace frequently worn stockings every few months. Check the manufacturer’s guidance and replace garments that are damaged, stretched, or no longer fit properly.

6. Choose a style you can comfortably wear

Comfort and ease of application matter. If putting on stockings is difficult because of limited flexibility, hand strength, or mobility, ask about donning aids or alternative compression options.

The 2025 SCAI guidelines identify difficulty applying and removing garments as an important barrier to consistent compression use.

Who Should Consult a Healthcare Professional Before Using Compression?

Compression therapy is appropriate for many people, but it is not suitable for every circulation problem.

People with known or suspected peripheral artery disease (PAD), reduced arterial circulation, certain skin conditions, or complex wounds should receive an individualized assessment before using compression.

Severe arterial insufficiency can make compression unsafe. The clinician may need to assess arterial circulation and determine whether any level of compression is appropriate.

People with new leg swelling, unexplained pain, suspected DVT, or significant changes in skin condition should seek medical evaluation rather than simply purchasing stronger compression stockings.

For people with venous ulcers, compression can be an important part of treatment, but it should be coordinated with appropriate wound care and circulation assessment.

Frequently Asked Questions About Compression Stockings for Venous Insufficiency

Are compression stockings good for venous insufficiency?

Compression stockings can help manage symptoms of chronic venous insufficiency, including leg swelling, aching, and heaviness. They do not cure the underlying vein valve problem. A healthcare professional can help determine the appropriate compression level and garment.

What compression level is best for venous insufficiency?

The appropriate level depends on the severity of the condition, circulation, symptoms, and treatment goals. Compression in the 20–30 mmHg range is commonly used for some people with venous disease, while higher pressures may be recommended for selected cases. Consult a healthcare professional before choosing a level.

Should I wear compression stockings every day?

Many people with chronic venous disease wear compression during the day as part of their treatment plan. The recommended schedule depends on the condition and garment. Follow your healthcare professional’s advice.

Can compression stockings make varicose veins go away?

No. Compression can help manage symptoms such as aching and swelling, but it does not remove existing varicose veins or permanently correct venous reflux.

Can I sleep in compression stockings?

Most people using ordinary daytime compression stockings for venous insufficiency do not need to wear them while sleeping. However, certain medical situations require different instructions. Follow your clinician’s recommendations rather than assuming all compression garments are intended for overnight use.

Do compression stockings prevent blood clots on airplanes?

Properly fitted graduated compression stockings may reduce asymptomatic DVT in some long-distance travelers, particularly those with increased risk. Not eNot every traveler needs them, and they do not replace individualized medical advice.

Give Your Legs the Support They Deserve

Whether you’re experiencing tired, aching legs or managing chronic venous insufficiency, compression stockings can be a valuable part of leg care.

For people with symptomatic venous disease, properly selected compression can help relieve discomfort and swelling. For people with venous ulcers, compression is an important component of evidence-based treatment. And for certain travelers, compression stockings may help reduce the risk of asymptomatic DVT.

The key is choosing the right garment, compression level, and fit for your individual needs.

At The Compression Closet, we encourage you to choose compression products from reputable manufacturers, follow fitting and care instructions, and consult a healthcare professional when you have questions about your circulation or medical condition.

Your legs carry you through every day. Give them the care and support they deserve.
