Venous Ulcers

Venous ulcers are the most common type of leg ulcer. They are caused by damage to the veins, which are responsible for bringing blood from various parts of the body to the heart through one-way valves. If the valves are damaged, blood can flow the wrong way down the veins, which results in a very high pressure in the veins when standing up. This abnormally high pressure in the veins damages the skin and leads to the ulcers.
