Many of us develop sores on our legs from trauma or other unknown reasons. Sometimes an open sore appears on the legs and it won’t heal. A sore is considered a non healing wound if it does not improve in 4 weeks or completely heal in 8 weeks. Non healing wounds are categorized by their underlying cause.
Most sores that won’t heal fall into 2 categories:
- Venous insufficiency ulcers
- Arterial insufficiency ulcers / diabetic ulcers
The following picture guide to open leg sores that won’t heal shows the differences in venous and arterial insufficiency ulcers. The picture guide also shows the many different appearances of venous insufficiency skin changes and open sores.
Venous insufficiency is by far the most common reason for open sores on the legs that do not heal. And, venous insufficiency accounts for 80-85% of non healing leg wounds. Typically, the legs swell. The swelling impairs oxygen and nutrients getting to the skin.
There are many different appearances of venous insufficiency. One appearance is that of red sores on legs. The skin is often red, scaly and itchy as in the picture below.
