Open Sores On Legs That Won’t Heal: Causes & Natural Treatment

An open sore on leg is an area of skin that is damaged below the knee. Sores or skin ulcers that are present for more than 6 weeks without healing are called non healing skin ulcers. They are often observed on legs as compared to other parts of body. These ulcers may be painful or without pain. The affected leg is swollen. One or both the legs may be affected.

When present on legs open sores are primarily found on the inner side of leg below the knee and above the ankle.

The base of open sore may be red or brown and black in color. The border may be irregular in shape and the surrounding skin may be warm and hot to feel. There may be white watery discharge or thick yellow pus draining from the sore.

There are ranges of condition which can cause open sores on leg that do not heal easily. They primarily occur due to stagnation of venous blood, narrowing of artery affecting blood circulation or due to involvement of nerves in diseases such as diabetes and leprosy. Open sores on leg seen and attended in their early stage can be treated much more easily rather than those which become large after a period of time.

What Causes Open Sores On Legs?

Open sores on leg which do not heal are usually caused by vascular diseases, diabetes, certain infections such as leprosy, and skin cancer. Non healing open ulcers can be categorized into various types such as:

Pressure sores, vascular sores, diabetic sores, marjolin’s ulcer, ulcers due to infective organisms, pyoderma gangrenosum.

  • Pressure sores in legs: Pressure sores develop in legs when the skin remains compressed for a long period of time. This leads to decrease in blood circulation and oxygen to the affected area, ultimately leading to tissue damage and formation of ulcers. Most pressure sores are found in lower limbs near the ankle and foot and on the buttocks. They occur in people who are confined to bed for long duration, or those who are unable to shift their position and having poor nutrition.
  • Vascular diseases: Majority of open sores develop due to insufficient circulation in veins and arteries. Varicose veins accounts for 50 to 60 percent of open non healing sores. In this condition the valves in the veins of lower leg become weak. As a result blood begins to stagnate in the lower leg. It leads to swelling, pressure and ulcer formation as it becomes chronic condition. Usually sores due to venous insufficiency develop in the medial region of ankle and around the calf. It can also occur due to decreased circulation of blood in the arteries caused due to narrowing of the arteries. Smokers and elderly individuals are often prone to formation of non healing ulcers in lower limbs due to reduced flow in the arteries. A minor scratch or abrasion in leg can lead to non healing sores. Impaired blood circulation to the affected site will reduce the healing response due to lack of nutrition provided in the blood after an injury.
  • Diabetes is one of the causes for sores in leg that is difficult to heal. The peripheral nerves in diabetes gets damaged which can trigger formation of ulcers especially in foot and in lower legs.
  • Pyoderma gangrenosum are tiny sores in legs which are painful and filled with pus. They coalesce to form large sores in few days after their formation. It is immune disease which has its association with other inflame related diseases or occurs in people having low immunity.
  • Skin cancer: It can also present with non healing sore on legs. Early diagnosis plays an important part in treating the condition. Any delay in treating the condition may require surgical procedure to treat the condition.
  • Leprosy caused by mycobacterium bacteria also leads to open sores that do not heal easily.
    Other deep skin fungal infections and antibiotic resistant staph infections are also known to cause non healing sores on legs.

    I have been dealing with dry, itchy skin and open sores on my legs for at least 7 to 9 years with no resolve. I have been to every dermatologist and my primary doctor where I live and also to Infectious Disease center and not a single doctor has been able to give me any medicine or diagnosis as to what I have. Last year the sores have started to spread to my arms, neck, chest and stomach areas. These are very painful open sores that itch and when scratched bleed profusely. What should be my next step and what kind of doctor should I see?

    I have several open sores on my legs. I had a golden staph infection about seven years ago, from shoulder surgery in operation theater. Ever since I constantly find it hard to heal.
    I have tried honey and Aloe Vera with little success.

    I have a sore on my leg and it has been almost three months since it first started. At first, I thought it was just an insect bite but itchiness was killing me. I kept scratching it. Then after two weeks it got bigger then after another week it started showing yellow discharge. It doesn’t hurt instead it itches so badly that I wanted to scrape it with a knife. Now another one is starting right next to it and it is spreading all over my legs. If anyone know what can heal this kind of sores kindly let me know.
