Non-healing leg sores, or leg ulcers, are often caused by poor blood circulation (venous or arterial), diabetes leading to nerve damage, or pressure, with common culprits being malfunctioning vein valves (venous insufficiency) causing blood pooling or blocked arteries starving tissue of oxygen, delaying healing significantly and requiring medical attention.
Causes of Slow Healing Wounds on Legs
Slow-healing sores or wounds on the legs, ankles, or feet are a common symptom of underlying health conditions. Some common causes include: Diabetes. Autoimmune infection or other immune system issues.
arterial leg ulcers – caused by poor blood circulation in the arteries. diabetic leg ulcers – caused by the high blood sugar associated with diabetes. vasculitic leg ulcers – associated with chronic inflammatory disorders such as rheumatoid arthritis and lupus. traumatic leg ulcers – caused by injury to the leg.
Venous ulcers are often described as shallow, irregularly shaped wounds, often accompanied by visible skin changes surrounding the broken skin. Many venous leg ulcers have a red base that oozes, although the presentation of the wound can vary depending on medical history and stage of healing.
Treatment for leg ulcers
Venous leg ulcers are open sores that occur on the lower legs, typically between the knee and the ankle, due to poor blood circulation.
Most small wounds heal naturally with time, but home remedies, such as aloe vera, antibacterial ointment, or honey, may speed up the healing process.
Signs and symptoms of diabetic ulcers
Diabetic ulcers are caused by hyperglycemia. Notably, most nontraumatic amputations are due to diabetic ulcers. The borders of diabetic ulcers are usually raised and round. They are often located on the bottom of the feet and are associated with skin cracks, blisters, and sores.
A venous leg ulcer can develop after a minor injury if there's a problem with the circulation of blood in your leg veins. This happens when the pressure inside the veins increases. This constant high pressure can gradually damage the tiny blood vessels in your skin and make it fragile.
Leg ulcers are deep, slow-healing sores on the legs or feet that form when the skin breaks down and doesn't heal properly. They are common, especially in older people. Unlike a shallow wound or graze, an ulcer affects deeper layers of the skin. They often leave a scar after they heal.
If you notice your skin lesion is increasing in size or shape, is causing you severe pain, is bleeding or leaking pus or won't heal as you expected — or if you have other associated symptoms like fever, joint pain, swelling or anything concerning to you — visit your healthcare provider immediately.
Symptoms of an infected leg ulcer can include:
A sepsis scab is not your ordinary skin abrasion. Imagine it as a dark, ominous cloud on your skin, often appearing red, swollen, and warm to the touch. Unlike regular scabs, sepsis-related scabs are typically surrounded by discolored skin and may ooze pus or other fluids.
What is chronic venous insufficiency? Chronic venous insufficiency occurs when your leg veins don't allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves don't work well, blood can also flow backwards.
A vascular specialist is skilled in diagnosing and evaluating the underlying causes of leg ulcers. They will assess your symptoms, medical history, and perform tests like a Doppler study or venogram to identify the root cause.
The incidence for malignant tumours in chronic leg ulcers was suggested to be around 2. 2% (8) with an incidence for SCC of 0. 4% 8, 9 being significantly higher than the incidence for SCC in the normal population (10).
People with nonhealing wounds are at risk for: Bone infections such as osteomyelitis, which may lead to limb loss (amputation). Cellulitis, a potentially severe bacterial infection of the skin and layers beneath the skin.
An infected leg ulcer must be treated appropriately or the infection could spread, creating further complications such as sepsis.
Diagnosis and Treatment
Appearance: Neuropathic ulcers are often round and have thick calluses on the surrounding skin. The depth of the wound depends on how much trauma the skin has been subjected to.
To help treat a venous ulcer, the high pressure in the leg veins needs to be relieved.
A skin wound that doesn't heal, heals slowly or heals but tends to recur is known as a chronic wound. Some of the many causes of chronic (ongoing) skin wounds can include trauma, burns, skin cancers, infection or underlying medical conditions such as diabetes. Wounds that take a long time to heal need special care.
Research consistently supports the use of occlusive ointments, such as Aquaphor and Vaseline, in speeding up wound healing. These ointments create a protective barrier that locks in moisture, a key factor in the healing process. Keeping a wound hydrated prevents the formation of scabs, which can delay healing.
Wounds generally heal faster and better when kept covered and moist, not uncovered, because a moist environment promotes faster skin cell growth, reduces scab formation, lowers pain, and minimizes scarring, while keeping the wound protected from dirt and germs; however, small, clean cuts might be left uncovered if they don't get dirty, but covering them with ointment and a bandage is usually best for optimal healing.
