Spider veins are small varicose veins that have a bluish, weblike
appearance. Varicose veins are twisted and enlarged veins near the surface of
the skin that most often occur in the legs and ankles.
Spider veins do not usually cause symptoms, although some people
may feel mild itching or burning.
Spider veins are common and generally are not a serious health
problem. Most people can manage varicose veins with home treatment, such as
exercising, wearing compression stockings, and elevating the legs.
Other treatments include sclerotherapy, in which a chemical
injection into a vein makes it close; or laser therapy, which scars and closes
a vein. A closed vein loses its source of blood and dies. This makes it likely
to fade or disappear.
