What is venous disease?

Healthy leg veins contain valves that open and close to assist the return of blood to the heart. Venous reflux disease develops when the valves that keep blood flowing out of the legs and back to the heart become damaged or diseased. As a result, vein valves will not close properly, leading to symptoms of pain, swelling, swollen legs and skin changes and skin ulcers.

Venous reflux disease is progressive and the symptoms can worsen over time if left untreated.
