What Causes Rash and Itching on Lower Legs?
Skin Conditions
1. Eczema
Eczema, also known as atopic dermatitis, is a chronic skin condition that can cause a rash and itching on the lower legs. It is characterized by dry, itchy, and inflamed skin. Eczema can be triggered by certain substances, such as detergents, soaps, and allergens.

Infections
4. Fungal Infection

Other Causes
6. Dry Skin
Dry skin can lead to itching and a rash on the lower legs. This is especially common during the colder months when the air is dry and moisture is lost from the skin.
7. Allergic Reaction
An allergic reaction to certain medications, foods, or environmental factors can cause a rash and itching on the lower legs. This can include hives, redness, and swelling.
