Understanding and Managing Swollen Feet

3. Chronic venous insufficiency

Chronic venous insufficiency is a condition that occurs when the flow of the deep or superficial venous blood is impaired. Essentially, the valves in the leg veins do not work properly, and blood cannot flow effectively back to the heart. This causes blood to pool in the legs, leading to swelling. Chronic venous insufficiency can lead to many other symptoms, including discolored skin, burning or itching in the legs, flakey skin, leathery-looking skin, varicose veins, or ulcers near the ankles. Treatment can include compression therapy, medication, surgery, and lifestyle changes.
