What Are Spider Veins?

Spider veins are small, web-like red or blue veins visible on the surface of the skin, especially around the thighs, calves, or face. They’re usually caused by increased pressure within smaller veins close to the skin.

Varicose Veins: Deeper and More Painful

Varicose veins are larger, bulging veins caused by valve failure deeper in the venous system. They often protrude above the skin and may cause pain or throbbing.

Do Spider Veins Mean Vein Disease?

Often, yes. Even though spider veins appear mild, they can be early signs of venous reflux. At Sheen Vein (Aesthetics and Functional Medicine), we perform ultrasound vein mapping to detect deeper issues that may not be visible.

Symptoms to Watch For

If you have spider veins and notice:

• Leg fatigue or heaviness
• Burning sensations
• Restless legs at night

—it’s time to evaluate for early venous insufficiency.
