Spider veins can appear anywhere on the body but are most common on the legs. They appear because of an increase in pressure. When blood collects in the veins, the veins enlarge, making them more noticeable and sometimes uncomfortable.
While elevating your legs or using compression stockings may help reduce the appearance of leg veins, they typically do not go away on their own without additional treatment.
The most common treatment to remove leg veins in sclerotherapy. This treatment involves the injection of a solution into the veins, which causes the vein to collapse and be absorbed.
