Varicose veins are gnarled, enlarged veins. Any vein may become varicose, but the veins most commonly affected are those in your legs and feet. That’s due to the fact that standing and walking upright increases the pressure in the veins of your lower body.
For most, varicose veins — a common, mild variation of varicose veins — are simply a cosmetic concern. For other people, varicose veins can cause aching pain and discomfort. Oftentimes, varicose veins can lead to more serious health problems.
