Varicose veins are a very common problem, mostly among women, but men can suffer from it too. Varicose veins are groups of small veins that appear on your thighs or face. They can be bluish, purple or red and are often painful. They occur when your veins dilate or overfill with blood.
They appear when veins aren’t functioning as they should. Instead of preventing blood from flowing backward, they start to accumulate it, resulting in the raised, swollen and red appearance.
