Spider Veins

Spider veins are small, dilated blood vessels that appear close to the surface of the skin. They can be red, blue, or purple and often have a web-like appearance. While commonly seen on the legs and face, their presence can vary between individuals. Many people find them to be a cosmetic concern rather than a medical one.

  • What exactly are spider veins?
    MedlinePlusMay 2026

    Spider veins are small, swollen veins that you can see just under your skin, usually in the legs. They happen when the one-way valves in your veins weaken, causing blood to back up and pool in the vein.

  • Why do my legs feel heavy and achy with spider veins?
    MedlinePlusMay 2026

    Spider veins can cause heaviness and achiness because blood is pooling in the veins instead of flowing smoothly back to your heart. This extra pressure and swelling in the vein can make your legs feel tired and uncomfortable.

  • Can I get spider veins in other parts of my body besides my legs?
    MedlinePlusMay 2026

    Yes, spider veins can form in other parts of your body besides your legs, though the legs are the most common place. They can appear anywhere veins have weak valves that allow blood to pool.

  • How does being overweight affect my risk for spider veins?
    MedlinePlusMay 2026

    Extra weight puts more pressure on your veins and makes it harder for them to pump blood back to your heart. This increased strain can damage the valves in your veins and lead to spider veins.

  • Will having spider veins increase my chances of getting blood clots?
    MedlinePlusMay 2026

    Spider veins are different from deep vein blood clots and don't typically cause blood clots. However, if you have concerns about clot risk, talk to your doctor about your specific situation.
