Causes of Legs Itching & Burning
Chronic Venous Insufficiency
If you are experiencing persistent itching and burning in your legs, it may be a result of chronic venous insufficiency (CVI). CVI develops as your valves don’t function properly, causing blood to flow back to your legs, instead of to your heart.
When valves weaken or become damaged, blood flows backward and pools in the legs, ankles and feet. The condition often causes varicose veins and spider veins to develop, and the feeling of itching and burning skin.
Nerve Damage and Irritation
When small nerves in the legs are irritated or damaged, it can cause an itching and burning sensation even when the skin looks normal. This can happen with conditions like diabetes or past injuries, and can also occur with chronic vein problems like chronic venous insufficiency or severe varicose veins. The sensation may feel like pins and needles or tingling.
Skin Conditions and Dryness
Sometimes, the root cause of itching and burning is deeper, and other times it is on the surface of the skin. Dry skin and eczema can cause persistent itchy or burning skin, usually accompanied by visible skin changes. However, vein problems can sometimes cause an eczema-like skin rash called venous stasis dermatitis, so it is important to be screened for vein conditions if you notice skin changes or itching.
Peripheral Artery Disease
Peripheral artery disease (PAD) reduces blood flow to the legs and can cause burning or itching, especially with walking or activity. With PAD, this symptom and others, like cramping or skin that is cool to the touch, subside with rest. The cause of itching with this condition is similar to venous diseases: a lack of circulation in the legs, leading to reduced oxygen and nutrients.
Lymphedema
Skin swelling due to lymphedema can dry out the skin and make it feel itchy. Causing the urge to scratch. The right care is important since patients with lymphedema are more likely to contract bacterial infections from cuts on the skin.
Lipedema
Lipedema is a chronic condition that causes abnormal fat distribution, usually in the legs. There can be tenderness and sensitivity, along with burning and itching sensations in the affected areas.
