Varicose veins also show up in other areas of the body as hemorrhoids, esophageal varices and in the scrotum. They form because the blood flow is too slow and the vein piles up with the excess. Another possible reason is that the valve in the vein is not working properly so the blood drops down from gravity and collects in the veins of the legs. Varicose veins are more likely to occur in women than in men. Leg veins become bigger, blue and twisted.
Most people feel severe pain in the area, swelling, and a constant itch.
Blood can pool in the veins and the tissues won't get enough blood and nutrients causing the skin to become thin, hard, dry and discolored. Ulcers may also form in the area. Sitting down with the legs raised is the only way that these problems will be relieved. Bumping can cause severe bleeding so contact with the vein should be limited. The legs have of two systems of veins.
