If you have spider veins, you are not alone; many people suffer from spider veins. For many, they can be an embarrassing problem when they occur in easy-to-spot locations like on the thighs and calves.
Spider veins are small, thread-like veins that are generally blue or red in color that form when blood becomes caught in the blood vessels under the skin. Although spider veins are not normally a cause for medical concern, they can be very difficult to treat with just over-the-counter products.
Sclerotherapy is a highly effective in-office treatment for spider veins that involves a quick injection directly into the vein. The solution causes the vein to collapse and forces the pooled blood back into the body. Over the next few weeks, the vein gradually becomes less and less apparent until it is no longer an obvious feature on the skin.
