Now that Chronic Venous Insufficiency is making headlines, remember—it’s always been newsworthy.  At USA Vein Clinics, we’ve been advocating for awareness and treatment long before the spotlight.  Chronic Venous Insufficiency (CVI) is a common but often misunderstood condition that affects how blood flows through the veins in your legs. If you have a personal or family history of varicose veins or blood clots, your risk may be even higher. Over time, the valves inside the veins lose their ability to keep blood moving upward, leading to the symptoms associated with CVI.
