SPIDER VEINS
Spider veins are those small weblike networks of red, purple and blue vessels that are easily visible through the skin and found most commonly on the legs and ankles. Women are more susceptible than men to develop them and those with blood relatives with spider veins are more predisposed to developing these roadmap veins. Heredity seems to play an important role in the development of spider veins. There is little scientific evidence that crossing the legs causes spider veins.
