Medical compression stockings apply graduated pressure, strongest at the ankle and lighter higher up, helping veins return blood to the heart. They relieve varicose vein symptoms and swelling, are used after vein treatment, and help prevent clots in certain situations. Pressure class and length are chosen per condition, and they shouldn't be used without advice if you have weak arteries.
Compression stockings are one of the simplest and oldest treatments for venous disease, yet many people wear them wrongly or choose the wrong class or size and get little benefit.
How do they work?
Medical stockings apply graduated pressure: strongest at the ankle, decreasing up the leg. This helps the veins push blood upward and reduces swelling and heaviness.
When are they used?
- Relieving varicose vein and venous insufficiency symptoms: heaviness, aching and swelling.
- After laser, radiofrequency or sclerotherapy treatment.
- Treating and preventing recurrence of venous ulcers.
- After deep vein thrombosis to reduce swelling and complications, as your doctor advises.
- Prevention on long journeys for some higher-risk people.
- During pregnancy to ease varicose vein symptoms.
Pressure classes
Measured in mmHg and usually grouped into classes: light for prevention and mild fatigue, medium for most varicose veins, swelling and after treatment, and strong for ulcers and severe swelling. Your doctor sets the right class.
Length
- Knee-high: the most used and easiest to wear, enough for most cases.
- Thigh-high or tights: when varicose veins involve the thigh, or after some procedures as advised.
The right size
Set by measuring ankle and calf circumference and leg length, ideally in the morning before swelling. Too loose gives no pressure; too tight causes pain and may impede circulation.
How to put them on
- Put them on in the morning before the leg swells.
- Turn the stocking inside out to the heel, insert the foot, then roll it up gradually without wrinkles.
- Rubber gloves make it much easier.
- Take them off at night unless your doctor says otherwise.
- Wash in lukewarm water and replace every few months as they lose pressure.
