Varicose veins refer to swollen and enlarged veins that can be seen on the surface of the skin. They often appear bulging, twisted, and blue or purple in color. Untreated varicose veins get worse over time. Numerous treatment options are available to treat varicose veins. They can be treated by compression stockings or with the latest modalities like Endovenous Laser Ablation Therapy (EVLT) and foam sclerotherapy.
