Chronic venous insufficiency is a vein disease in the legs. Veins take deoxygenated blood back to the heart. The veins in the leg makes use of valves to work against gravity. Dysfunctional valves allow blood to leak back down towards the feet. The pooled blood increases pressure and eventually leads to spider and varicose veins. Signs of venous insufficiency include leg cramps, itching, leg ulcers, tightness in the calves, and leg or ankle swelling. Venous insufficiency symptoms may also include skin discoloration on the lower legs. The causes of venous insufficiency are weight gain, pregnancy, and infections or inflammations of the vein (Phlebitis). A specialist vein doctor will use a diagram of leg veins to aid your understanding of the condition. It is important to check the qualification and certification of a vein doctor before booking an appointment. Ask for before and after superficial thrombophlebitis pictures of cases they handled in the past. Still have more questions like; can venous insufficiency be cured? What is stasis?
