What are varicose veins?

Varicose veins are knotted swollen veins that collect abnormal amounts of blood, which causes them to appear dark blue or purple. It is more common for the veins in the legs and feet to become varicose. Varicose veins can range from being simply a cosmetic concern for some people to causing pain and discomfort to others. The presence of varicose veins can also be an indication that someone is at a greater risk of other circulatory complications.
