What are venous leg ulcers?

Venous leg ulcers are a type of skin wound that occurs when blood flows back through tiny veins in the body. They're most often found on both legs, but can also occur around one or both arms depending upon where they arise from within your system: breathe-eat-surge up near heart level; stand all day at work with no break--that's why these areas suffer more than others! The symptoms may not seem serious enough for intervention unless other factors such as poor circulation coupled together cause problems like pain during activities which makes them difficult to fully enjoy life.
