Q16. What are varicose veins?

Varicose veins-which afflict 10% to 20% of all adults-are swollen, twisted, blue veins that are close to the surface of the skin. Because valves in them are damaged, they hold more blood at higher pressure than normal. That forces fluid into the surrounding tissue, making the affected leg swell and feel heavy. Unsightly and uncomfortable, varicose veins can promote swelling in the ankles and feet and itching of the skin. They may occur in almost any part of the leg but are most often seen in the back of the calf or on the inside of the leg between the groin and the ankle. Left untreated, patient symptoms are likely to worsen with some possibly leading to venous ulceration.
