Compression Stockings – NICE / NHS Guide

Chronic venous disease occurs when the valves in the leg veins fail to function correctly. Blood can pool in the lower legs, leading to heaviness, aching, swelling, skin changes, and, in some cases, open ulcers near the ankles.

Graduated compression stockings are tighter at the ankle and gradually less firm up the leg. This gentle squeeze supports the vein walls, improves venous return and encourages excess fluid to move out of the tissues. Over time, this can reduce symptoms, support the healing of venous leg ulcers, and lower the risk of recurrence after healing.

In UK practice, compression stockings may be recommended for:

• Symptomatic varicose veins
• Venous eczema and skin changes such as haemosiderin staining, lipodermatosclerosis and atrophie blanche
• Healed venous leg ulcers to reduce the risk of recurrence
• Superficial thrombophlebitis
• Oedema due to chronic venous insufficiency
• Short periods after some vein procedures where advised by the surgeon

Compression is one part of a broader care plan. It does not replace a complete vascular assessment. Before stockings are prescribed, you should undergo a careful review to ensure they are safe and suitable for you.

NICE And NHS Guidance Overview

NICE and other guideline groups look at the available evidence and produce recommendations for the care of people with venous leg disease. These are used across NHS services to maintain consistent, safe standards of care.

Documents include:

• NICE guidance on varicose veins
• SIGN guidelines on the management of chronic venous leg ulcers
• Royal College of Nursing guidance on nursing management of leg ulcers
• Wounds UK best practice statements on compression hosiery

These sources stress that compression stockings should only be prescribed after assessment of arterial circulation, skin condition and the person’s ability to use them. They also highlight the importance of correct sizing, regular review and shared decisions with the patient.

Vein Solutions follows the same principles. Every patient is assessed by a vascular specialist, usually with duplex ultrasound, so that compression stockings are used appropriately and, where needed, combined with modern treatments such as endovenous laser, radiofrequency ablation, foam sclerotherapy, or cyanoacrylate glue.

Pre-Prescription Clinical Assessment

Before compression stockings are prescribed, a detailed assessment is needed. This is standard practice in both NHS and specialist clinics.

Your clinician will ask about:

• Any previous deep vein thrombosis or pulmonary embolism
• Past leg trauma or operations
• Previous leg ulcers, cellulitis or recurrent infections
• Current medication, including steroids, anticoagulants or drugs that may affect skin or circulation
• Family history of varicose veins or venous disease
• Lifestyle factors such as standing for long periods, long journeys and smoking

This information helps to identify risk factors and conditions that may change the type or level of compression that is safe for you.

A careful examination of both legs looks for:

• Varicose veins and reticular veins
• Venous dermatitis and eczema
• Brown staining of the skin due to haemosiderin deposition
• Areas of thickened or hardened skin, such as lipodermatosclerosis
• Pale scarred patches known as atrophie blanche
• Oedema pattern and signs that suggest a non-venous cause
• Skin breaks, ulcers or wounds

Peripheral pulses are checked at the ankles to give an early indication of arterial supply. Any significant pain on walking, pale or cold feet, or hair loss on the legs raises the possibility of arterial disease and indicates that further tests are needed before compression is used.

The skin needs to be resilient enough to cope with stockings. Thin or fragile skin tears easily and may be damaged when stockings are applied or removed. Active venous ulcers may require compression bandaging at first rather than stockings.

Allergies to certain fibres or previous reactions to elastic garments should be noted. In some cases, alternative fabrics or liners can be used.

Ankle Brachial Pressure Index And Arterial Safety

The safe prescription of compression stockings depends on an adequate arterial blood supply to the legs.

An ankle-brachial pressure index (ABPI) uses a small Doppler probe and a blood pressure cuff to compare ankle and arm blood pressures.

• A result between about 0.8 and 1.3 usually indicates that standard compression stockings can be used, so long as there are no other concerns.
• A result below 0.8 suggests significant arterial disease. In this situation, standard compression stockings can reduce blood flow too much and should not be used. Specialist vascular assessment is needed.
• A result above 1.3 may mean the arteries are stiff or calcified. This can give misleading readings. Again, vascular referral is recommended before compression is considered.

ABPI testing is widely used through NHS leg ulcer services, community nursing and vascular clinics.

Ongoing Monitoring

People with venous disease can later develop arterial disease. For this reason, guidelines suggest repeating ABPI at intervals, often every six to twelve months, or earlier if symptoms change. New calf pain on walking, changes in skin colour or non-healing wounds should always prompt review.

At Vein Solutions, consideration of arterial circulation is part of every vascular assessment. If there is any concern, further vascular imaging or referral is arranged before compression therapy is started or changed.

Compression Class

Stockings come in different compression classes. These classes indicate the amount of pressure applied at the ankle.

In the UK, manufacturers commonly use three primary classes for medical compression hosiery:

• Class 1 provides light compression and is often comparable to travel socks or mild support stockings

• Class 2 provides moderate compression and is frequently used for symptomatic venous disease

• Class 3 provides stronger compression and is reserved for selected patients with adequate arterial supply and more severe venous problems

Guidance suggests prescribing the strongest compression that the person can manage safely and comfortably. However, patient tolerance and arterial status always guide the final choice.

Indications By Class

Class 1 is often used for mild symptoms, early varicose veins or in people who cannot tolerate stronger stockings. It may also suit individuals who want some support on long flights but do not have significant venous disease.

Class 2 is widely used for conditions such as:

• Symptomatic varicose veins
• Venous eczema and skin changes
• Healed venous leg ulcers to lower the chance of recurrence
• Superficial thrombophlebitis

If class 2 stockings do not provide sufficient symptom relief and arterial supply is adequate, class 3 stockings may be considered for some patients, often under specialist supervision.

Stockings After Deep Vein Thrombosis

Guidance on elastic stockings after a proximal deep vein thrombosis has changed over time. Current UK guidance does not recommend routine prescription of elastic compression stockings solely to prevent recurrent venous thromboembolism or post-thrombotic syndrome. They may still be used in some cases to help with symptoms such as swelling or discomfort, where a vascular specialist considers them appropriate.

This is another reason why individual assessment is essential.

Selecting Stocking Length

Length choice is usually between below-knee and thigh-length stockings.

Below Knee Compression

Below-knee stockings are commonly the first choice. They are:

• Easier to put on and remove
• Often more comfortable, especially in warmer weather
• Less likely to roll down or wrinkle at the thigh

They are recommended for preventing recurrence in many people with healed venous leg ulcers, provided the primary disease is in the lower leg. They can also control swelling that is limited to the calf and ankle.

Thigh Length Compression

Thigh-length stockings may be advised when:

• Varicose veins extend well above the knee
• Swelling involves the whole leg rather than just the lower part
• There has been extensive vein surgery or treatment higher in the thigh

Some people find thigh-length stockings less comfortable or more likely to slip. Reports from clinical studies suggest that they are not clearly more effective than below-knee stockings for many indications, including prevention of post-thrombotic syndrome, yet they can be harder to tolerate.

Evidence and Patient Preference

Research has not clearly shown that one length is consistently better than the other for long-term outcomes. For that reason, patient preference is very important.

Guidance such as NICE and CKS encourages shared decision-making. The stocking that a person can put on, keep on and feel comfortable wearing throughout the day is often the most effective option in practice.

At Vein Solutions, we discuss lifestyle, work clothing and cosmetic concerns so that stocking length is chosen together with the patient.

Open Toe and Closed Toe Designs

Another choice is between open-toe and closed-toe stockings. Both provide the same compression class when appropriately fitted. The difference lies in comfort and practicality.

Closed toe stockings are commonly prescribed and suit many people. They provide full coverage of the foot, which may help limit toe swelling. They also sit neatly inside most types of footwear.

Open toe stockings may be preferable if you:

• Have arthritic or clawed toes that rub inside closed-toe garments
• Have a fungal nail infection or other conditions that require topical treatment
• Have a long foot in relation to calf size and struggle to find a closed-toe stocking that fits both correctly
• Like to wear your normal socks over the stockings for comfort or appearance

They can be slightly easier to apply in some cases, and some people find them more comfortable in warmer weather.

Open-toe stockings can sometimes ride up the foot. This may cause the toes to swell and feel uncomfortable. In some people, the band at the toe edge can irritate painful toe joints.

If any discomfort, redness, or swelling occurs in the toes or the foot, you should discuss this with your clinician. A change in style, size or class often solves the problem.

Measurement and Sizing

Correct sizing is essential. Stockings that are too tight can cause pain, numbness or skin damage. Stockings that are too loose will not provide the intended compression.

Measurements are usually taken with the person sitting, feet flat on the floor, or, occasionally, standing, as directed by the brand. For below-knee stockings, typical measurements include:

• Ankle circumference at the narrowest point above the ankle bones
• Calf circumference at the widest point of the calf
• Foot length for closed-toe designs from the heel to the tip of the longest toe

For thigh-length stockings, an extra measurement is taken around the broadest part of the thigh.

Each manufacturer provides sizing charts that convert these measurements into stocking sizes. All measurements must fall within a single size range. If not, a different brand or a made-to-measure option may be needed.

If legs are swollen, measurements are best taken in the morning when swelling is at its lowest. Some patients will first need a period of compression bandaging to reduce severe oedema before stocking measurements are taken.

Measurements can be taken by trained staff in a clinic, a pharmacy, or a community setting. If this is not possible, carers may be shown how to measure, but complex cases should be referred back to a clinician or community nurse.

Made To Measure Compression

People with very large or very slim legs, misshapen limbs or significant asymmetry between the legs may need made-to-measure hosiery. Guidance from sources such as the Journal of Community Nursing supports the use of made-to-measure stockings when standard sizes cannot provide accurate compression.

These can be arranged through NHS leg ulcer services or prescribed in specialist clinics such as Vein Solutions.

Daily Use, Application and Skin Care

Once stockings have been correctly prescribed and fitted, using them properly each day is key to success.

In most cases, compression stockings are:

• Put on soon after waking, before the legs swell
• Worn throughout the day
• Removed before going to bed

If there is a reason they must stay on overnight, such as short periods after some procedures, you will be given specific instructions and a limit on the number of days this should continue. In general, stockings should not be worn continuously for more than seven days without removal and skin inspection.

Application Aids

People with arthritis, reduced hand strength, back problems or mobility issues can find stockings difficult to manage. There are many application aids, such as frames, sliders or gliding devices, that can make the process easier.

Family members, carers and community nurses can also help, especially in the early stages. NICE and RCN guidance recognise that support with the application can improve long-term use.

At Vein Solutions, we demonstrate practical techniques for putting on and taking off stockings. Patients are encouraged to practise in the clinic until they feel confident.

Skin Care

Daily skin care is critical. Gentle fragrance-free emollients are recommended once stockings are removed, often in the evening. This helps reduce dryness and itching.

Greasy creams should not be applied immediately before stockings are put on, as they can break down the fibres and reduce the effectiveness of compression. Any rash, blistering or open areas under the stockings should be reported promptly.

Replacement, Washing and Care

Even the best stockings lose their elasticity with wear and washing.

Most guidance suggests replacing medical compression stockings every three to six months. People who wear them daily and are active may need new pairs closer to the three-month mark.

You should have at least two garments so that one can be worn while the other is washed and dried.

Each time stockings are replaced, new measurements are recommended. Body weight, muscle bulk, and swelling can change over time, potentially altering the size needed.

Washing And Drying

Stockings should be:

• Hand-washed or machine-washed on a gentle cycle at about forty degrees, if the manufacturer allows
• Rinsed thoroughly to remove detergent
• Dried away from direct high heat, such as radiators or tumble dryers

High temperatures can damage elastic fibres and reduce compression. You should check regularly for signs of wear, such as thinning areas, ladders, wrinkles that do not smooth out or reduced firmness at the ankle.

Review Schedule and Ongoing Monitoring

Compression therapy is not a one-off prescription. It needs regular review.

Guidelines recommend reviewing patients every 3 to 6 months. At review, your clinician will:

• Reassess leg symptoms such as pain, heaviness and swelling
• Examine the skin for new changes, ulcers or signs of irritation
• Check that stockings still fit properly and are within their replacement period
• Discuss comfort, any difficulty with daily use and your overall satisfaction

Depending on this review, the class or length of stocking may be changed, or other treatments may be considered.

ABPI is usually repeated every 6 to 12 months, or sooner if new symptoms suggest arterial disease. This ensures that compression remains safe as circumstances change.

In NHS settings, local policies will guide where these tests are carried out. In a specialist clinic, tests may be performed on-site or in partnership with local vascular departments. Vein Solutions can share results and care plans with your GP for joined-up care.

Supporting Comfort and Adherence

Compression stockings only work if they are worn regularly. It is common for people to struggle at first. Studies suggest that many patients do not wear their stockings as prescribed.

People are more likely to continue with stockings when they understand how they help. Simple explanations, such as linking regular use to fewer episodes of swelling, better comfort after standing and lower risk of ulcer recurrence, can make a real difference.

At Vein Solutions, time is taken to answer questions and address any worries about appearance, work clothing or social activities.

Some patients prefer natural skin tones, others feel more confident in darker shades such as black, navy or grey. Men often choose darker colours that resemble socks, which can be worn with business or casual shoes without drawing attention.

If stockings feel too tight, roll down, dig into the skin or cause discomfort, this should be reviewed. Adjusting the class, changing the brand, or moving from thigh-length to below-knee stockings often improves comfort.

Common issues include:

• Feeling too warm, particularly in summer
• Itching or dry skin
• Stockings sliding down
• Pain or numbness in toes or feet

Simple measures such as lighter fabrics, appropriate emollients, silicone grip tops or different lengths can help. Pain, colour change or any sign of skin breakdown under the stocking should prompt urgent review, as these may indicate that compression is too firm or arterial supply is impaired.

Compression Stockings after Vein Procedures

After minimally invasive varicose vein treatments such as endovenous laser therapy, radiofrequency ablation, foam sclerotherapy, or cyanoacrylate glue, short-term compression is often recommended.

The purpose in this setting is usually to:

• Reduce post-procedure bruising and discomfort
• Support treated veins in the early healing period
• Limit short-term swelling

The exact type of stocking and the duration of wear vary with the procedure and the individual. Some protocols advise continuous wear for a few days, followed by daytime wear for 1 to 2 weeks, though details are always adjusted to the patient.

At Vein Solutions, you will receive clear written instructions and a demonstration before and after your procedure so that you feel confident about using compression during recovery. Long-term need for stockings is reviewed once healing is complete and venous circulation has improved.

Lifestyle and Vein Health

Compression stockings work best as part of a broader approach to vein care. Helpful lifestyle measures include:

• Regular walking or gentle exercise to activate the calf muscle pump
• Simple ankle and calf movements when sitting for long periods
• Raising the legs on a footstool when resting, if practical
• Weight management and a healthy diet
• Smoking cessation support through NHS services if you smoke

For many people, a combination of lifestyle changes, compression and, when appropriate, vein treatment provides the best improvement in symptoms and long-term leg health.

Vein Solutions Approach to Compression Therapy

Vein Solutions is a specialist vascular clinic led by Mr Sameh Dimitri, an experienced consultant vascular surgeon who has treated thousands of patients using modern minimally invasive techniques.

Your treatment starts with a detailed consultation that includes:

• Clinical examination of your legs
• Duplex ultrasound scan to map the veins and confirm the cause of symptoms
• Review of your medical history, medication and lifestyle

This allows us to identify whether your symptoms are due to varicose veins, chronic venous insufficiency, pelvic reflux, post-thrombotic changes or another cause.

Individual Treatment Plan

Compression stockings are considered in the context of your overall condition and aims. For some people, they are a short-term measure as part of leg ulcer care or after a procedure. For others, they provide longer-term comfort where intervention is not needed or not suitable.

If modern treatments such as endovenous laser, radiofrequency ablation, foam sclerotherapy or glue closure are appropriate, these are discussed with you, including likely outcomes and recovery.

Throughout, care is aligned with NICE and other UK guidance so that you benefit from both current evidence and the experience of a specialist vascular team.

Ongoing Support

After any procedure or when stockings are prescribed as a standalone treatment, follow-up is provided to assess symptom relief, stocking fit, and skin health. Adjustments are made as your condition changes and, where helpful, communication with your GP is maintained.

If you have varicose veins, leg swelling, skin changes, or a history of venous ulcers, and would like specialist advice, Vein Solutions offers comprehensive vascular assessment and a full range of modern treatments, including guidance on compression stockings when suitable.
