Varicose veins are swelled twisted veins. Varicose veins can occur at any place but more commonly in the legs as veins in there are subject to a lot of strain and pressure. Varicose veins have a superficial concern. But, they can be painful and can make one prone to serious problems. And, as they look hideous and can become the reason for social anxiety. Varicose veins are mainly caused due to pressure and incapacity to transfer the blood in the whole body due to faulty veins. The blood flows towards the heart by one-way valves in the veins. When the valves become vulnerable or vitiated, blood can accumulate in the veins. This creates the veins to become expanded. Sitting or standing in the same position can trigger this ailment, raising the pressure within the veins. The veins can be strained from the increased stress. This may impair the walls of the veins and ruin the valves.
