What are varicose veins?

ANSWER

Varicose veins appear just beneath the surface of your skin. You get them when the valves inside your veins become weak or damaged. Normally, the valves help blood flow up to your heart. When they don’t work right, blood pools inside your veins. They swell and become large and rope-like.
