Venous Ulcers are sores that typically develop around the ankle area.
They occur because of a problem in the veins in the legs. Normally, veins carry blood back up to the heart. But, in people who have venous insufficiency, the venous valves do not work well and leak, resulting in higher pressures in the leg veins. This increased pressure can lead to venous ulcers. Oftentimes, treatments can be done to improve blood flow, but strict adherence to compression garments is always recommended.
