When should I see my GP about varicose veins? 

Varicose veins are a common condition where veins become swollen and twisted, usually in the legs. While many people manage mild symptoms at home, there are specific clinical indicators that suggest the condition requires a professional medical assessment. Understanding these signs is essential for preventing complications such as skin damage or circulatory issues. This article explains when the transition from self-care to a clinical consultation is necessary. 

What We’ll Discuss in This Article 

• Identifying red flag symptoms that require a medical review 

• How persistent pain and heaviness affect clinical priority 

• Recognising skin changes such as discolouration or eczema 

• The significance of non-healing sores or ulcers on the lower leg 

• Differentiating between cosmetic concerns and medical necessity 

• When sudden swelling or redness becomes an urgent matter 

• Preparing for a consultation regarding your venous health 

Identifying Red Flag Symptoms for a GP Visit 

You should see a GP about varicose veins if they are causing significant pain, discomfort, or if the skin over the veins becomes sore and irritated. Clinical priority is often given to cases where the veins interfere with daily activities or show signs of advanced venous disease, such as skin discolouration, hardening of the tissue, or the development of a venous leg ulcer. 

While many individuals view bulging veins as a visual issue, a GP assessment is necessary when the functional failure of the vein valves leads to physical symptoms. If your legs feel heavy, achy, or if the skin feels tight and itchy, these are indicators that the internal pressure in your legs is high. A medical professional can help determine if you require specialist intervention to prevent the condition from worsening. 

• Persistent aching that interferes with sleep or work 

• Swelling in the ankles or feet that worsens throughout the day 

• Intense itching or burning sensations over the affected veins 

• A feeling of restlessness in the legs during the evening 

Causes of Advanced Venous Symptoms 

The progression of varicose veins into more serious symptoms is primarily caused by chronic venous hypertension. This occurs when the one-way valves in the leg veins fail to close properly, allowing blood to pool in the lower limbs. Over time, this stagnant blood increases the pressure on the vein walls and the surrounding skin tissues, leading to inflammation and physical discomfort. 

This sustained pressure can eventually force fluid and red blood cells into the skin, which is the primary cause of the discolouration and hardening often seen in advanced cases. Factors such as a history of deep vein thrombosis, multiple pregnancies, or occupations that involve long periods of standing can accelerate this process, making a GP review more likely as the valves face continuous strain. 

Triggers for Seeking Medical Advice 

Specific triggers often prompt a patient to seek a medical opinion, usually when home management strategies like elevation or compression are no longer providing sufficient relief. These triggers are clinical signs that the venous system is struggling to maintain healthy circulation against the pull of gravity. 

• Non-healing wounds: A small scratch or bite on the lower leg that does not heal within two weeks is a major trigger for a clinical review. 

• Skin discolouration: The appearance of brown or purple patches around the ankles suggests that blood is leaking into the skin. 

• Surface inflammation: If a vein becomes suddenly hard, red, and painful, it may indicate a superficial clot that requires monitoring. 

• Spontaneous bleeding: If a varicose vein bursts or bleeds through the skin, it is a significant medical trigger that requires immediate attention. 

Differentiation: Cosmetic vs. Medical Priority 

It is important to distinguish between spider veins, which are typically a cosmetic concern, and varicose veins that carry a medical risk. Spider veins are small, flat, red or blue lines that do not usually cause pain or lead to skin damage. In contrast, true varicose veins are bulging and twisted, indicating a failure in the deeper venous system that may require treatment to prevent ulcers. 

Feature	Cosmetic Concern (Spider Veins)	Medical Priority (Varicose Veins)
Appearance	Fine, web-like lines on the skin.	Bulging, rope-like, or twisted.
Pain Level	Usually painless or very mild.	Persistent aching, throbbing, or heaviness.
Skin Health	Skin remains healthy and soft.	Skin may be hard, dark, or scaly.
Complications	No risk of ulcers or major clots.	Risk of ulcers, bleeding, and phlebitis.

My final conclusion 

Deciding when to see a GP about varicose veins depends on the severity of your physical symptoms and the health of the skin on your lower legs. While many cases remain stable, red flags such as skin discolouration, persistent pain, or wounds that do not heal require a professional medical assessment. Early intervention is the most effective way to manage venous hypertension and prevent the development of chronic complications like leg ulcers. 

If you experience severe, sudden, or worsening symptoms, call 999 immediately.
