A sore is an ulcer or an open wound. A sore forms when the skin breaks down and allows the entry of bacteria and air pollutants into the underlying tissues. There is always redness and swelling around an ulcer, sometimes the base of an ulcer itself is fiery red. An ulcer is usually seen on the legs, though it can occur in any part of the body.
What are the Causes of Red Sores?
The main reason for red sores on leg is insufficient blood supply to the skin and tissues. It can occur due to variety of reasons.
Venous ulcers occur when the veins carrying the impure blood from lower legs towards the heart may not function to its optimum.
Arterial ulcer can result due to peripheral arterial disease. Due to deposition of cholesterol in the leg arteries, the blood circulation in the lower leg is impaired. Poor oxygenated blood supply to the leg tissue can damage the tissues of the leg and some of them get destroyed (necrosed) forming an ulcer. These leg sores are usually round and painful. They appear on the toes or on the heels. Occasionally they appear bluish due to lack of oxygen. Arterial sores can be itchy and red.
Diabetic ulcer is a form of neuropathic ulcer. Due to neuropathy in diabetes, there is decreased sensation in the legs and toes. The leg becomes vulnerable to an injury. Generally neuropathic sores are observed on toes and heels. The sores appear red and itch sometimes.
Pressure sores are most common in elderly and those who are bed ridden. Constant pressure on a particular portion of the leg can cut the blood and oxygen supply to that area. They are usually on the bony prominences.
Treatment and Prevention for Itchy Red Sores on Legs
Primarily aim is to prevent the formation of red leg sores in legs in the first place.
To prevent leg sores that are itchy due to venous insufficiency, wear compression stocking. They help to push the blood back to the heart and prevent pooling of blood in the lower leg.
To prevent arterial sores, modify your diet. Eat less oily and fatty food. Instead eat food rich in vitamins, and fibers as it prevents atherosclerosis in the leg arteries. Stop smoking as it is one of the cause for peripheral artery disease.
Do not sit or stand in one position for long period to prevent pressure sores.
