Spider VS Varicose Veins Spider veins or varicose veins are usually caused by a hereditary predisposition to developing them, but there are certain things that can accelerate their appearance or worsen them, like pregnancy, or hormones, like birth control pills. But there are other factors for both men and women, like prolonged standing.
Spider veins are just a collection of abnormally dilated capillaries, or very small blood vessels.
They get their name from their web-like appearance. Varicose veins are larger veins that have gotten dilated and can actually bulge out and have a ropelike appearance. The total time and cost depends on how bad the veins are. Immediately after the treatment, and lasting about a week, it's normal to have some bruises. Spider veins are going to leave minimal bruises but bigger veins can leave bigger bruises.
