Spider veins are similar to varicose veins, but smaller. Spider veins are considered cosmetic and most insurance carriers do not cover their treatment. Nevertheless, spider veins also may cause symptoms, including aching, throbbing, and itchy legs.

The body tends to continue producing spider veins despite successful treatment. For this reason, follow-up intermittent treatments are often necessary.

Spider veins are small, red, purple, or blue thread-like veins on the surface of the skin.
