Varicose Veins vs. Spider Veins: Understanding the Difference

Many people notice visible veins and wonder what they mean. Varicose and spider veins are both common—but distinct—conditions. This article explores how to tell them apart, what they might indicate about your health, and when to consider treatment.

What Are Varicose Veins?

Veins with weakened valves that allow blood to pool, leading to enlarged, ropey, blueish veins under the skin—commonly on legs, feet, or ankles.

Symptoms: aching, heaviness, swelling, skin changes, ulcers; can signal chronic venous insufficiency (CVI)

What About Spider Veins?

Smaller, superficial clusters of red, blue, or purple lines—more cosmetic than medical.

Symptoms: They are usually asymptomatic, though they may rarely cause mild itching or burning.
