What causes itching of the skin on the lower leg?

Itchy skin on the lower leg may be caused by various factors, primarily including the following: 1. Environmental factors: Cold and dry environments can easily lead to loss of skin moisture, causing dryness of the lower leg skin and subsequent itching. 2. Skin diseases: Conditions such as ichthyosis and stasis dermatitis directly affect the health of the lower leg skin, leading to itching. 3. Allergic reactions: Exposure to certain allergens, such as specific clothing materials, foods, or medications, may trigger allergic reactions on the lower leg skin, resulting in itchiness. 4. Circulatory problems: Conditions like varicose veins in the lower limbs can increase venous pressure and impair blood return, leading to stasis dermatitis characterized by localized itching. Other possible causes include dry skin, food allergies, scabies, pruritus, and neurodermatitis. To ensure accurate diagnosis and proper treatment, it is recommended to seek medical attention promptly when experiencing persistent itching on the lower leg skin.
