Spider veins are similar to varicose veins – which are swollen, twisted veins caused by the weakening of valves resulting in improper blood flow – except they are closer to the surface of the skin and typically less painful. However, as with any condition, if unmonitored and left untreated, progression and worsening will occur.
- A large number of people who have spider veins will see them in the legs.
- The further away the vein is from the heart, the more effort it takes to pump properly. Plus the weight of gravity, and for many, the effects of a sedentary lifestyle, puts extra pressure on the veins’ valves.
- Spider veins also appear on the face, and one reason for this is excessive exposure to the sun.
