Compression stockings can be an important part of the treatment of vein disease, both before and after your procedures. But, with all the options out there, it can be overwhelming to choose the one that is best. Here we will talk about the different types of stockings and which one may be best for you.
Quick Answer: For most people with vein symptoms, the right choice is a graduated medical-grade compression stocking, usually knee-high, at 15 to 20 or 20 to 30 mmHg. Thigh-high stockings or pantyhose are often used after vein procedures or when symptoms extend above the knee. White T.E.D. hose are meant for bed rest after surgery, not for daily vein care. The best stocking is one that is measured correctly, feels firm but not painful, and that you will actually wear every day. Anyone with poor leg circulation should have their arteries checked before using compression.
T.E.D Hose: These are the white stockings that are used in many hospitals after surgical procedures. These stockings typically have 8-18mm Hg compression. They are designed for use after surgery when you are lying down and do not work well for managing venous symptoms or for after vein treatments.
Medical Grade Compression stockings: Medical grade compression stockings come in several different forms and typically range from 15-20mm Hg to 40-50mm Hg. They come in different lengths from knee-high to thigh high and pantyhose.
Knee highs are best for conservative management of symptoms and for long term stocking use due to the ease of getting them on and on and their relative comfort for daily wear. For conservative management, I usually recommend 15-20mmHg or 20-30mmHg if tolerated well. As a bonus, knee highs come in lots of fun styles and patterns and are also available in a trouser sock form. Most knee highs are available in open toe and closed toe depending on patient preference.
Thigh-high stockings are commonly used after vein procedures and can be used for conservative management as well if the patient’s symptoms are above the knee. They are also available in a range of compression, but after treatment 20-30mm Hg is typically recommended. They can also be purchased in the open toe and closed toe form and have a silicone beaded band at the top to ensure that the stockings stay in place.
Pantyhose can also be used for after treatment if the patient prefers something that comes up to the waist. Pantyhose are available in all the levels of compression and in open toe or closed toe form. Maternity pantyhose are also available for pregnant patients.
Leggings are similar to pantyhose but they stop at the ankle and do not cover the foot. They are often available in different patterns and are designed to be worn in a similar way to fashion leggings. Because of the risk of foot swelling with higher compression grades, these stockings are usually only available in 15-20mm Hg or less compression. This makes them ideal after cosmetic spider vein treatment but not for post procedure use after endovenous ablation or phlebectomy.
Athletic compression socks and sleeves: These socks generally have thicker sole and forefoot cushion and are designed for use during and after athletic activity. Some studies have shown these types of compression socks to improve athletic performance and can be seen being worn by elite runners and athletes. They range in compression from 10-15 to 20-25mm Hg compression.

How Compression Stockings Work
Compression stockings are not just tight socks. Medical stockings are made with graduated compression, meaning the pressure is strongest at the ankle and gradually decreases up the leg. That gradient supports the vein walls, helps the remaining valves close more effectively and gives the calf muscle something firm to push against when you walk. The result is less blood pooling in the lower leg, less fluid leaking into the tissues and less of the heavy, achy feeling that comes with vein disease.
It is important to understand what compression can and cannot do. Stockings treat symptoms and help control swelling, and they play a central role in healing venous ulcers. They do not repair damaged valves or make varicose veins disappear. When symptoms come from a leaking vein, compression is often the first step and a partner to treatment, rather than a cure.
Compression during pregnancy
Pregnancy is one of the times compression helps most. Rising blood volume, hormonal relaxation of the vein walls and pressure from the uterus on the pelvic veins all make leg swelling and varicose veins more likely. Many women find that 15 to 20 or 20 to 30 mmHg stockings, put on before getting out of bed, ease aching and swelling considerably. Maternity pantyhose with a stretchy belly panel are comfortable for some, while others prefer knee-highs. If you develop sudden swelling in one leg, or swelling with headaches or vision changes, contact your obstetric provider promptly rather than relying on compression.
Choosing the Right Compression Level
Compression is measured in millimeters of mercury (mmHg). The number on the box describes the pressure at the ankle. Higher is not automatically better; the right level depends on your symptoms, your circulation and what you can comfortably put on and wear.
| Compression level | Typical uses | Prescription needed? |
|---|---|---|
| 8 to 15 mmHg (light) | Tired legs, long days on your feet, travel | No |
| 15 to 20 mmHg (moderate) | Mild aching, mild ankle swelling, spider veins, pregnancy, after cosmetic sclerotherapy | Usually no |
| 20 to 30 mmHg (firm) | Varicose veins with symptoms, moderate swelling, after ablation or phlebectomy, chronic venous insufficiency | Usually yes |
| 30 to 40 mmHg (extra firm) | Severe swelling, skin changes, healed venous ulcers, post-thrombotic syndrome | Yes |
| 40 mmHg and above | Severe lymphedema or specific medical needs under close supervision | Yes |
In our practice, patients who are new to compression often start at 15 to 20 mmHg to get used to the feeling, then move up to 20 to 30 mmHg if they need more support and tolerate it well.
Getting the Right Fit: Measuring for Compression Stockings
A stocking that does not fit will either fail to help or be so uncomfortable that it ends up in a drawer. Medical stockings are sized by measurements, not by shoe size.
- Measure in the morning, before swelling builds through the day
- Ankle: the narrowest point just above the ankle bone
- Calf: the widest part of the calf
- Leg length: from the floor to just below the bend of the knee for knee-highs
- Thigh: the widest part of the upper thigh for thigh-highs or pantyhose
If your measurements fall between sizes or your legs are an unusual shape, ask about different brands or made-to-measure options. A good fitter or medical supply store can help, and we are happy to guide patients through the process.
Signs the fit is wrong
- The top band rolls down or digs in, leaving a deep groove
- Bunching or wrinkles behind the knee or at the ankle
- Toes that tingle, feel numb or turn pale or blue
- New pain, blisters or red marks that do not fade quickly after removal
Tips for Putting On and Wearing Compression Stockings
The most common complaint we hear is that stockings are hard to get on. These techniques make a real difference:
- Put them on first thing in the morning, before your legs swell
- Make sure your legs are dry; a little talc or cornstarch helps in humid weather
- Turn the stocking inside out down to the heel, slip your foot in, then roll it gradually up the leg rather than pulling from the top
- Wear rubber gloves for grip and to protect the fabric from rings and nails
- Consider a donning aid, such as a wire frame or a slippery foot sleeve, if you have arthritis, back problems or limited reach
- Smooth out wrinkles so pressure is even along the leg
- Take them off at bedtime unless your doctor has told you otherwise
In a hot, humid climate like Houston’s, lighter fabrics, open-toe styles and knee-highs tend to be easier to wear through the summer. Some patients keep two pairs so one can be washed and dried while the other is worn.
Who Should Not Wear Compression Stockings Without a Check?
Compression is safe for most people, but it can be harmful when the arteries in the legs are narrowed. Squeezing a leg that already has poor blood supply can reduce flow even further and damage the skin. You should be evaluated before using firm compression if you have:
- Known or suspected peripheral arterial disease, or pain in the calves when walking that eases with rest
- Weak or absent pulses in the feet, or cold, pale feet
- Diabetes with reduced feeling in the feet
- Fragile skin, open wounds or skin infections on the legs
- Severe heart failure with significant leg swelling
A simple ankle-brachial index test compares blood pressure at the ankle and arm and tells us whether compression is safe and at what strength.
Remove your stockings and seek urgent care if you notice:
- Toes or feet that become numb, cold, pale or blue and do not recover after removing the stocking
- Sudden swelling, pain and warmth in one leg, which may be a deep vein thrombosis
- Chest pain or sudden shortness of breath
- Skin that blisters, breaks down or becomes very painful under the stocking
Compression After Vein Procedures
After vein treatment, compression helps reduce bruising, tenderness and swelling, and supports the treated veins as they close. The exact instructions vary by procedure and by patient, but as a general guide:
- After sclerotherapy for spider veins: often 15 to 20 or 20 to 30 mmHg for several days to two weeks
- After endovenous ablation: commonly thigh-high 20 to 30 mmHg for one to two weeks
- After ambulatory phlebectomy: compression stockings, sometimes with a wrap over the first day, then stockings for one to two weeks
Follow your own discharge instructions, since your vein specialist may adjust these based on what was treated. You can read more about specific procedures on our endovenous thermal ablation and ambulatory phlebectomy pages.
How We Evaluate Whether Compression Is Right for You
At Premier Vein and Vascular Center, compression is part of a plan, not a one-size-fits-all prescription.
- Focused history. We ask about aching, heaviness, swelling, skin changes, prior clots, your job and how long you are on your feet.
- Examination. We examine your legs, check pulses in the feet and look for skin changes that suggest more advanced venous disease.
- The right test. An ankle-brachial index checks arterial flow when needed, and a venous duplex ultrasound looks for reflux or clots in the leg veins.
- A clear plan. We recommend the type, length and strength of stocking that suits you, and explain whether vein treatment could reduce or remove the need for daily compression.
Caring for Your Stockings
Compression fabric gradually loses its elasticity, so even a well-fitted stocking becomes less effective over time. Most stockings worn daily need replacing about every three to six months, or sooner if they look stretched or feel loose.
- Hand wash or machine wash on a gentle cycle in cool or lukewarm water
- Use a mild detergent without fabric softener or bleach
- Air dry away from direct heat; avoid the dryer unless the label allows it
- Remeasure your legs if your weight or swelling changes significantly

Frequently Asked Questions
How many hours a day should I wear compression stockings?
Most people wear them from the time they get up until they go to bed, which is when the legs are under the most pressure. They are usually taken off at night unless your doctor has advised otherwise.
Should I sleep in compression stockings?
Generally, no. When you lie down, gravity no longer pulls blood into the legs, so compression is less needed. Some patients are told to wear them overnight for a short time after a procedure, so follow your specific instructions.
Can compression stockings make varicose veins go away?
No. Compression relieves aching, heaviness and swelling and helps prevent worsening, but it does not repair damaged valves. Treating the leaking vein is what removes varicose veins.
Does insurance cover compression stockings?
Coverage varies. Some plans cover prescription-strength stockings for specific conditions such as venous ulcers, while many plans do not. Insurers often require a trial of compression before approving vein procedures, so keep your receipts.
Are knee-high or thigh-high stockings better?
Knee-highs are easier to put on and are enough for most symptoms below the knee, so they are the most popular for everyday use. Thigh-highs or pantyhose are preferred after vein procedures on the thigh or when swelling and symptoms extend above the knee.
Can I wear compression stockings when flying?
Yes. Moderate compression of about 15 to 20 mmHg can reduce leg swelling and discomfort on long flights. Walk the aisle, flex your ankles and stay hydrated as well, especially if you have a history of clots.
Why do my compression stockings hurt?
Pain usually means the stocking is the wrong size, the compression level is too high, the fabric is bunched or the top band is rolling. Remeasure your legs in the morning and try a different size or strength, and stop wearing them and get checked if your toes go numb, pale or blue.
