A Varicose Vein Scan is a non-invasive test used to assess the health of veins, particularly in the legs, to detect conditions like varicose veins and venous insufficiency. Varicose veins occur when veins become swollen and twisted, often causing discomfort, swelling, and skin changes. Venous insufficiency is a condition where veins struggle to return blood to the heart, leading to symptoms like leg swelling and chronic pain. This scan helps identify these issues early, enabling timely treatment to prevent complications and improve quality of life.
