One of the most common medical disorders in the United States that is also one of the most underdiagnosed is chronic venous insufficiency (CVI) It's a disease of the veins, which makes it difficult for blood to return to the heart from the legs. It happens when the wall of the veins and/or the valves stop working properly and blood starts leaking into tissue or pooling. It can happen in your deep veins, which are the largest ones that are deep in your body and run through the muscle, your superficial veins that are close to your skin's surface, or your perforating veins that actually connect the deep and superficial veins. If you have CVI, you may experience symptoms such as leg swelling, pain, and throbbing while standing, muscles aches, leg cramps, itching, even varicose veins. Interventional Cardiologist Dr. Robert Coronado joins hosts Kym McNicholas and Dr. John Phillips to talk about the prevalence of CVI, how to talk to your doctor about getting tested, how its diagnosed, and treatment options.
