Symptoms Of Varicose Veins

Mild Foot And Ankle Swelling

Two systems of veins help pump venous blood back to the heart and lungs to be replenished with oxygen. Superficial veins are located just beneath the surface of the skin, and the deeper veins are located closer to the bones and can not be seen by looking at the skin of the legs. Superficial veins can be seen around the ankles, top of the foot, calves, and thighs as twisted bulges. Deep vein insufficiency may not be seen as large bulges from the skin, but it can result in chronic swelling of the ankles, feet, and legs. Since the blood is not being circulated back to the heart, due to valves that are not working properly, it pools in the legs, causing swelling in the feet and ankles. This condition is called edema. If the edema continues for a long time, it can cause discoloration of the overlying skin, leading to venous stasis dermatitis. It can also cause an ulcer to develop on the skin.
