Chronic Venous Insufficiency: Managing Varicose Eczema and Leg Health in the UK

Chronic Venous Insufficiency (CVI) is a long-term condition where the valves in the leg veins do not work effectively. In a healthy circulatory system, these valves ensure that blood flows upwards towards the heart, fighting gravity. When these valves become damaged or weakened, blood can flow backwards and pool in the lower legs—a process known as venous reflux.

According to NHS and NICE guidance, CVI is a progressive condition. If left unmanaged, the increased pressure in the veins (venous hypertension) can cause fluid to leak into the surrounding tissues, leading to swelling, skin changes, and eventually, open sores known as venous leg ulcers. It is particularly common in the UK among older adults, individuals with a history of Deep Vein Thrombosis (DVT), and those who spend long periods standing or sitting.

Varicose eczema, also referred to as stasis or venous eczema, is a specific type of skin inflammation that develops in people with CVI. The high pressure in the veins causes small amounts of blood and fluid to leak into the skin, triggering an immune response. This leads to the characteristic symptoms of the condition.

Common Symptoms of Varicose Eczema

• Skin discolouration: Red, brown, or purple patches, usually around the ankles.
• Itching and dryness: The skin may feel tight, itchy, and extremely dry.
• Scaling and crusting: In flare-ups, the skin may become flaky or weep fluid.
• Lipodermatosclerosis: Over time, the skin can become hard, tight, and scarred, often described as having an 'inverted champagne bottle' appearance.
• Atrophie blanche: Small, white, scarred areas of skin that are prone to breakdown.

The management of CVI focuses on improving circulation and protecting the skin. In the UK, the primary line of treatment follows NICE clinical knowledge summaries, which emphasise a multi-modal approach.

• Compression Therapy: The 'gold standard' for CVI. Medical-grade compression stockings apply graduated pressure to the leg, helping valves close and encouraging blood flow. A GP or nurse must first perform a Doppler test to ensure the arterial circulation is healthy before compression is started.
• Skincare (Emollients): Keeping the skin hydrated is crucial to prevent cracks and infections. Applying unperfumed moisturisers (emollients) several times a day helps maintain the skin barrier.
• Topical Steroids: For active flare-ups of varicose eczema, a GP may prescribe a mild to moderate steroid cream, such as hydrocortisone or betamethasone, to reduce inflammation and itching.
• Leg Elevation: Elevating the legs above the level of the heart for 30 minutes, three to four times a day, can significantly reduce oedema (swelling).

Beyond medical intervention, lifestyle modifications are essential for managing chronic conditions like CVI. Patients are encouraged to remain active; calf muscle exercises, such as walking or ankle flexes, act as a pump to push blood upwards. Weight management is also key, as excess weight increases the pressure on the venous system.

It is equally important to avoid prolonged periods of inactivity. If your job involves standing for long hours, try to take regular breaks to sit and elevate your legs. Conversely, if you sit at a desk, ensure you stand up and walk every hour to stimulate circulation. Following these simple steps can prevent the progression from mild varicose veins to more severe chronic venous insufficiency.

Managing a long-term condition can be challenging, but many aspects of CVI and varicose eczema can be addressed through a private online GP service. You should consider booking a consultation if:

• You have noticed new, persistent swelling in your lower legs or ankles.
• You are experiencing itchy, red, or discoloured patches of skin that are not improving with over-the-counter moisturisers.
• You need advice on the correct type of compression therapy or a referral for a Doppler ultrasound.
• You require a prescription for topical treatments to manage an eczema flare-up.
• You want a second opinion on your current management plan to ensure it aligns with the latest UK health standards.

An online doctor can review your symptoms via video call, provide evidence-based advice, and issue private prescriptions or sick notes where appropriate, saving you time and providing peace of mind from home.

The most serious complication of unmanaged CVI is a venous leg ulcer. These are chronic wounds that take weeks or months to heal and are highly susceptible to infection (cellulitis). By addressing varicose eczema and venous hypertension early, you significantly lower the risk of skin breakdown. If you notice any small 'nicks' or breaks in the skin that do not heal within a week, it is vital to seek medical advice immediately to prevent a full ulcer from forming.
