What are varicose veins?
A person with varicose veins has enlarged, prominent veins under the surface of the skin. Veins are thin-walled vessels that return blood to the heart. Tiny valves inside the veins prevent blood flow from reversing direction. Damage to valves allows blood to collect in the veins, causing them to swell. Varicose veins are most common in the legs and feet. About 20 percent of adults have varicose veins.

What are the symptoms of varicose veins?
Symptoms of varicose veins include large, swollen veins in the legs. In addition, small veins may become visible beneath the skin in the legs.

How does the doctor treat varicose veins?
Treatment for varicose veins includes keeping the legs elevated while sitting, regular exercise, and support hose. Usually, varicose veins do not require treatment unless a person develops venous insufficiency. Treatment for severe varicose veins may include surgery.
