Varicose Veins
  1. What are varicose veins?
    Varicose veins are dilated tortuous (twisting) veins with weakened walls and valves that no longer close when they should. They occur in the lower extremities and are important for the health of the skin and superficial tissues. They appear as bulges under the skin of the erect individual and disappear when the limb is elevated above the heart.
