What can damaged vein valves cause?

ANSWER

Valves are flaps inside veins that control the direction of blood flow. Damaged valves can cause long-term blood pooling and swelling in your legs. That's called chronic venous insufficiency. Without treatment, fluid will leak into the tissues in your ankles and feet. It may eventually make your skin break down and wear away.
