Understanding the reason for varicose veins in legs can help patients recognize the importance of early diagnosis and treatment. Varicose veins develop when the valves inside the leg veins become weak or damaged, preventing blood from flowing efficiently back to the heart. As blood pools inside the veins, they become enlarged, twisted, and visible beneath the skin. USA Vein Clinics specializes in diagnosing and treating the underlying causes of vein disease.
