Varicose Veins are enlarged superficial veins in the legs, that may be the result of weakness in the walls of these veins. Over time, the veins tend to become less elastic because of the weakness. As a result, they stretch and thus become longer and wider. Then, in order for these veins to fit in the same amount of space they used to, they develop a snakelike appearance.
Because of their abnormal shape, the valves in the veins sometimes don’t function normally.
In addition to their enlarged appearance, other symptoms of varicose veins may include aching, tiredness in the legs, itching, and a rash. Less often, a painful ulcer may also occur that doesn’t heal. Treatment usually includes elevating the legs when lying or sitting, and may include the use of elastic or support stockings, especially when injection treatment and surgery are not desired. With injection treatment, an alternative to surgery, the veins are sealed so that blood can’t flow through them. With surgery, as many of the varicose veins as possible are removed.
