Varicose Veins

Brief summary: Varicose veins are enlarged and tortuous superficial veins. Beyond cosmetic concern, they may be associated with pain, heaviness, swelling, and, in some cases, skin changes or ulcers. ^[1][2]

Varicose veins are a venous disorder most commonly seen in the legs and usually develop in association with valve insufficiency in the superficial venous system. Their severity ranges from small spider veins to prominent bulging clusters. It is common to assume that they are only a cosmetic issue, but in some people they cause substantial symptoms such as pain, a sense of fullness, cramps, itching, swelling, and skin changes that worsen later in the day. In advanced venous disease, difficult-to-heal ulcers may also develop. ^[1][2]

Risk factors include family history, age, pregnancy, prolonged standing, obesity, and previous venous thrombosis. Even so, the presence of risk factors does not automatically mean severe disease will develop. Clinical evaluation aims not only to assess the visible appearance of the veins, but also to determine whether symptoms are compatible with venous insufficiency and whether the deep venous system is involved. For this reason, Doppler ultrasound is an important diagnostic tool in symptomatic patients. ^[1][3]

Symptoms often worsen as the day progresses or with prolonged standing. Leg heaviness, burning, throbbing, night cramps, itching, and swelling around the ankle are common. Brownish skin discoloration, hardening of the skin, or ulcer formation may suggest more advanced chronic venous disease. By contrast, sudden one-sided swelling, redness, and pain should not automatically be attributed to simple varicose veins; urgent conditions such as superficial thrombophlebitis or deep vein thrombosis need to be excluded. ^[1][2]

History, physical examination, and duplex ultrasound are the main pillars of diagnosis. Recent Society for Vascular Surgery and American Venous Forum guidelines recommend an evidence-based approach to diagnosis and treatment. The vein involved, the duration of reflux, and symptom burden all shape treatment choice. This allows personalized venous mapping instead of assuming that every varicose vein should receive the same procedure. ^[2][3]

Treatment options include lifestyle measures, leg elevation, movement, compression stockings in selected patients, and interventional procedures. Endovenous thermal ablation, foam sclerotherapy, and, in some cases, surgery may be appropriate. Current guidelines support minimally invasive endovenous techniques as effective and widely used options in suitable patients. Even so, the aim of treatment is not simply to improve the appearance of the vein, but to relieve symptoms, reduce complication risk, and improve quality of life. ^[2][4]

Compression stockings are not a single definitive solution for every patient. They may reduce symptoms in some people, but they do not eliminate the underlying venous reflux. They can be useful in venous ulcers, during pregnancy, or for temporary relief before intervention. However, the degree of long-term benefit differs individually. Guidelines also note that in appropriate symptomatic patients who are candidates for intervention, a mandatory trial of stockings is not always necessary. ^[2][3]

Movement plays an important role in living with varicose veins. Regular walking, avoiding prolonged immobility, weight management, and resting the legs can all help symptom control. Exercise does not “remove” varicose veins, but it supports venous return. Similarly, claims that herbal or cosmetic products can completely correct the veins are not strongly supported by evidence. It is not appropriate to rely only on advertising-based products instead of medical assessment. ^[1][2]

Sudden unilateral leg swelling, severe pain, redness, shortness of breath, or chest pain require urgent evaluation because they may be related to thrombosis. Varicose veins are common and often manageable, but if symptoms, skin change, or ulcer are present, vascular surgery or cardiovascular surgery evaluation is the most appropriate next step. ^[1][2][3]

The visible severity of varicose veins does not always match symptom burden. Some people with clearly visible veins have minimal complaints, while others with less obvious venous reflux may feel marked heaviness and pain. For this reason, decisions are not based on appearance alone; symptoms, skin changes, and ultrasound findings should all be considered together. ^[2][3]

Varicose veins may become more pronounced during pregnancy. Hormonal change, increased blood volume, and mechanical pressure from the uterus on venous return all contribute. In many individuals there is some regression after delivery, but in those who develop persistent venous insufficiency, further evaluation may be needed. Treatment options during pregnancy are also more limited, which changes the overall approach. ^[1][2]

Post-procedure care is also important. After endovenous ablation or sclerotherapy, walking, compression use, and follow-up appointments may be recommended. The goal is to support healing and monitor for complications or residual reflux. The exact protocol depends on the procedure performed and the clinic’s approach. ^[2][4]
