Spider veins of the legs often develop during pregnancy because of the high hormone levels and increased pressure on the legs from weight gain. Sclerotherapy injections can now be performed with less discomfort and risks using the new, FDA approved medication, Asclera. A tiny needle, the size of a hair, is inserted directly into the vein and the medication causes the vein to become inflamed and collapse. The damaged vein is naturally eliminated from your body in a few weeks. The physicians at NYLSC also use a variety of lasers for those who cannot have or do not want the injection treatment.
