    Varicose veins are twisted and dilated veins. Any vein can become varicose; however, the most frequently affected veins are those of the legs and those of the feet. That's because standing and walking with an upright posture increases the pressure in the veins of the lower part of the body.

    For many people, varicose veins and spider veins, a frequent mild variation of varicose veins, are simply an aesthetic problem. Sometimes, varicose veins cause more serious problems.
