Varicose veins are enlarged, twisted veins mostly seen in the legs. When we stand for a long time, the pressure in the veins increases, causing them to swell. The valves in the veins also become weak. They may be of only cosmetic concern or may cause pain, itching, and discomfort. There may also be discoloration of the skin or leg ulcers. Spider veins are prominent and thin veins near the skin. They are formed due to the pooling of the blood in surface veins by injury, obesity, or hereditary tendency. Varicose and spider veins can be treated by various methods.
