Skin ulcers are open sores caused by poor blood circulation. If you have poor blood circulation, then minor wounds (that otherwise would heal quickly) may not heal properly leaving that injury to develop into a painful skin ulcer. These sores and ulcers often become infected if not properly treated. The infection, left untreated, can spread to deeper tissue, bones, joints, and blood resulting in a very serious issue where immediate medical attention is needed.

These ulcers can appear on most parts of the body. Common places include the legs, hips, feet, buttocks, and back. Skin ulcers are more likely to affect elderly people.

Skin Ulcer

Skin ulcers typically look like a round open sore in the skin. The outer border of the sore might look raised and thick. As the ulcer forms, you may notice the skin discoloration in that specific area. It might begin to look red and feel warm. Those with darker skin tones will notice that their skin may look shiny or even turning blue. As the skin ulcer worsens, it will begin to look like a crater. It will typically begin to weep clear fluid or even blood.

Other symptoms depend on the type and severity of the ulcer. Depending on the type of ulcer you have, you may notice:

• Swelling
• Redness
• Tenderness
• Itchiness
• Pain
• Skin Discoloration
• Changes in skin texture
• Yellow or green pus (due to an infection)

Skin Ulcer Risk Factors

Certain risk factors can lead to an increased susceptibility to skin ulcers. It is important to know what these risk factors are to be vigilant and prepared, both for yourself and your loved ones. Below are a few risk factors:

• Pregnancy: Pregnancy can cause hormonal changes. Additionally, increased blood volume may cause leg vein problems.
• Cigarette smoking: Tobacco smoke is widely known for hardening arteries. This will no doubt disrupt proper blood flow.
• Limited mobility: Being bedridden, paralyzed, or using a wheelchair puts your skin under constant pressure. Arthritis can limit your movement, as well as injuries to the leg.
• Increasing age: Age is linked to atherosclerosis and venous insufficiency. Older populations are generally more susceptible to developing skin ulcers.
• High blood pressure: Hypertension, or high blood pressure, damages the arteries and disrupts blood flow.
• High blood cholesterol: High cholesterol increases artery narrowing and oxidative stress, which can disrupt proper blood flow.
• Obesity: Obesity raises your risk for diabetes, atherosclerosis, and increased pressure in your leg veins.
• History of blood clots: If you are prone to blood clots, then you are more likely to have blood flow issues.
