    Varicose veins and the associated problems relate to the veins not working properly. Healthy veins normally take blood from the feet back up to the heart. They have valves in them to ensure that the blood only flows in one direction. In some people the valves do not function properly, and the blood refluxes back down the leg. The pressure increases causing the veins to become distended. Fluid can leak out of the veins causing swelling. After a prolonged period of elevated pressures skin changes and ulcers can develop.
