Spider Veins

Also known as: Telangiectasias, Thread veins

Spider veins are small, damaged veins that appear on the surface of the skin as thin red, blue, or purple lines, typically on the legs or face. They are generally harmless but can be a cosmetic concern for many people. Spider veins are caused by backed-up blood from weakened or damaged valves and are often associated with similar risk factors as varicose veins.

Symptoms

Clusters of thin, web-like veins visible through the skin
Red, blue, or purple discoloration
Mild aching or burning in the legs
Itching around the affected veins
Most spider veins are asymptomatic
