The job of the vein is to collect blood from the body and bring it back to the heart. Healthy veins have one-way valves that move the blood in the correct direction – toward the heart – and prevent the blood from flowing backward. But with chronic venous insufficiency, these valves become broken or damaged, or the vein walls become weak, and blood flows in the wrong direction.
The most common cause of chronic venous insufficiency is blood clots in the deep veins. As noted above, it is also caused by malfunctioning valves in the veins.
Chronic venous insufficiency may include leg symptoms like achiness, throbbing, cramping, swelling, heaviness, itching, a burning sensation and restless leg.
If venous insufficiency is left untreated, it may lead to long-term problems like discoloration of the skin around the ankles, bleeding and ulceration. It is important to seek medical treatment of chronic venous insufficiency before symptoms become progressively worse. There are now state-of-the-art, minimally-invasive treatments available to help close varicose veins without removing them. These treatments help improve blood flow and alleviate symptoms, so you can start looking and feeling great again.
