About Venous Disease: Understanding Superficial Venous Reflux

Your legs have a network of veins. Healthy leg veins contain valves that open and close to assist the return of blood back to the heart. Venous reflux disease develops when the valves that keep blood flowing out of the legs become damaged or diseased. This can cause blood to pool in your legs and lead to symptoms such as pain, skin changes, swelling, leg heaviness and fatigue, skin ulcers, and varicose veins.
