What term is used to describe severe itching of the skin?

The term that describes severe itching of the skin is pruritus. This condition can be a symptom of various underlying issues, such as skin irritations, allergies, or systemic diseases. Pruritus can lead to significant discomfort and may cause individuals to scratch their skin, potentially leading to further irritation or skin damage.

Dermatitis refers more broadly to inflammation of the skin, which can cause various symptoms, including itching, but the term does not specifically denote just the itching aspect. Urticaria, commonly known as hives, involves raised welts on the skin that can be itchy, but again, it is a specific condition rather than a general term for skin itching. Eczema is a type of dermatitis that often involves itching but is defined by the presence of inflamed, red, and dry skin. Therefore, pruritus is the most accurate term when specifically referring to the sensation of severe itching.
