What Exactly Are Varicose Veins?

Varicose veins are swollen, discolored, twisted blood vessels that bulge under the surface of your skin. Your legs, feet, and ankles are where these blue or purple bulges most frequently appear, and they may also hurt or itch. Smaller red, twisted or purple lines that form near the surface of your skin are spider veins, which may surround varicose veins.
