Compression socks for varicose veins – how they work, when to use them, and what to expect

If you’ve started noticing heaviness, aching, or swelling in your legs, you might be wondering whether compression socks for varicose veins are the solution. As nurses in a vein specialist clinic, we often recommend compression therapy to patients—especially in the early stages of varicose vein development.

In this guide, we’ll break down how they work, what to expect, how to use them properly, and why they can help—but not cure—varicose veins.

What are compression stockings and how do they work?

Compression stockings for varicose veins are specially designed garments that apply gradual pressure to the lower legs. This compression supports vein walls and encourages blood to flow upwards, rather than pooling in the legs.

Here’s what the pressure does:

• Reduces vein diameter, improving valve function
• Increases venous return to the heart
• Minimises swelling and heaviness in the legs

Clinical research shows that properly fitted compression stockings can significantly reduce symptoms in patients with chronic venous insufficiency.

When are compression socks useful for varicose veins?

Compression is helpful in many situations:

• Early-stage varicose veins: to reduce discomfort and swelling
• After procedures like foam sclerotherapy or laser ablation
• During pregnancy, when venous pressure increases
• For people who stand or sit for long periods, such as teachers, nurses, or office workers

But compression stockings do not remove varicose veins. They are a symptom-management tool—not a cure.

Compression levels explained

Compression garments are measured in mmHg (millimetres of mercury) and are available in several classes:

Never self-prescribe high-level compression. An incorrect fit or excessive pressure can actually restrict circulation.

Tips for using compression stockings correctly

To get the most out of your compression socks:

1. Put them on first thing in the morning, before your legs swell.
2. Avoid folding or rolling them—this creates a tourniquet effect.
3. Replace them every 4–6 months to maintain proper elasticity.
4. Wash them gently—preferably by hand or on a delicate cycle.
5. Pair them with movement, such as light walking or stretching.

If compression doesn’t bring relief, you might be dealing with more advanced disease. In that case, it’s wise to consider a varicose veins consultation to explore curative options.

Compression versus treatment: why it’s important to know the difference

Wearing compression stockings can be an important part of managing the symptoms of varicose veins, but they are not a replacement for medical treatment. This distinction can be confusing for patients, especially when the symptoms are mild at first. Compression helps by supporting vein function and improving circulation temporarily, which makes it easier to get through long workdays or periods of travel. However, the underlying valve dysfunction that causes varicose veins will not go away with compression alone.

For those who want to address the problem at its root, medical treatment is the only lasting solution. Procedures such as endovenous laser ablation or foam sclerotherapy close off the faulty veins entirely, allowing healthy veins to take over. Many patients use compression during the healing period after treatment to maximise results and reduce swelling. So while compression is a useful tool, it’s best seen as a supportive measure—not the final answer.

Who should not wear compression stockings?

Compression therapy is not suitable for everyone. Avoid or consult your doctor if you have:

• Peripheral artery disease (PAD)
• Severe neuropathy or diabetic foot
• Skin infections on the legs
• Open ulcers (unless specifically prescribed)

If you're unsure, start with a check-up for varicose veins.
