👉 Aggressive veins, also known as varicose veins, are enlarged and twisted veins that can appear bulging or protruding from the skin surface. They typically develop due to weakened or damaged valves within the veins, which prevents blood from flowing back up towards the heart effectively. As a result, blood pools in the affected veins, causing them to stretch and become more visible under the skin's surface. Treatment options for aggressive veins include minimally invasive procedures like sclerotherapy or endovenous laser therapy, as well as lifestyle changes to improve circulation.
