Chronic venous insufficiency (CVI) is a condition that occurs when the veins in the legs have difficulty returning blood to the heart efficiently. It may cause symptoms such as leg swelling, aching, heaviness, fatigue, itching, or changes in the skin around the ankles. Risk factors can include prolonged standing or sitting, obesity, age, and a history of blood clots or vein problems. Diagnosis may involve a physical examination and venous duplex ultrasound. USA Vein Clinics provides personalized evaluations for vein conditions.
