Varicose veins are abnormally enlarged, bulging and often bluish-looking veins. They may also cause dull, nagging, achy pains. This usually occurs in the lower extremities, especially if you spend a lot of time standing, simply due to the fact that there is more and constant pressure exerted on the legs. The cause of varicose veins is a result of the malfunctioning of the valves inside the veins. These valves close like gates if blood tries to run in the wrong direction, but if these valves fail to work properly, blood is forced to flow back down the leg causing superficial veins under the skin to swell as the blood builds up, a bit like a dam. As well as the visible swelling of these veins, which can be seen as purplish-red and bluish marks, restless legs, sore legs, itching of the skin, leg cramps and a feeling of heaviness in the legs are all signs of varicose veins. Why these veins fail is not completely understood but it may be due to a weakness in the valve itself or in the vein wall.
