When Varicose Veins Are More Than Cosmetic

Varicose veins are enlarged, twisted veins that develop when vein valves stop working properly and blood begins to pool. While they may appear on the surface as blue or purple veins, they can also cause aching, heaviness, or swelling in the legs - signs that the underlying condition may be more than cosmetic.

At San Francisco Vein & Vascular Institute, we focus on the diagnosis and treatment of symptomatic varicose veins that impact circulation and comfort, not on cosmetic vein care.

Why Varicose Veins Develop

Healthy veins have one-way valves that direct blood toward the heart. When those valves weaken, blood can flow backward, leading to increased pressure in the veins. Over time, the veins stretch and become visible beneath the skin.

Common contributing factors include:
• Family history of venous disease
• Standing or sitting for long hours
• Hormonal changes or pregnancy
• Aging
• Obesity or excess weight

Symptoms That May Require Medical Evaluation

Not all varicose veins are just cosmetic. You may need evaluation if you notice:
• Aching or heaviness in the legs
• Swelling in the ankles or calves
• Burning, itching, or throbbing discomfort
• Skin discoloration or thickening near the veins
• Nighttime leg cramps

These symptoms may signal chronic venous insufficiency, a progressive condition that affects circulation and tissue health.

Medical Treatment Options for Symptomatic Veins

When lifestyle changes like leg elevation, exercise, or compression stockings aren’t enough, minimally invasive procedures can help improve circulation and reduce discomfort.

Treatments performed at our clinic include:
• Endovenous Ablation: Uses laser or radiofrequency energy to close diseased veins and redirect blood flow.
• VenaSeal™ Closure System: A safe medical adhesive that seals faulty veins through a tiny catheter without general anesthesia or downtime.
• Ultrasound-Guided Sclerotherapy: Used selectively for medically necessary treatment of residual or refluxing veins,.

When to Seek Care

If you’re experiencing leg swelling, pain, or heaviness, it’s time to consult a vascular specialist. Early treatment can prevent complications such as skin changes or ulcers and help restore healthy circulation. Because symptomatic varicose veins are a medical condition, treatment is typically covered by insurance. Our specialists can evaluate your vein health and recommend the best medical treatment options.
