What should you know about reason for body itching?

Itching with dry, cracked skin may fit [Asteatotic Eczema](/conditions/asteatotic-eczema/), while a long-standing itchy, inflamed pattern can occur with [Atopic Dermatitis](/conditions/atopic-dermatitis/). A new product, detergent, or metal can trigger [Contact Dermatitis](/conditions/contact-dermatitis/). Moist folds with soreness may occur with a [Skin Yeast Infection](/conditions/cutaneous-candidiasis/). Thick plaques, flat purple bumps, or intense nighttime itch with affected household contacts point toward different assessments, including [Psoriasis](/conditions/psoriasis/), [Lichen Planus](/conditions/lichen-planus/), or [Scabies](/conditions/scabies/). Raised fleeting welts are characteristic of [Hives](/conditions/urticaria/).

Use a fragrance-free moisturiser, keep showers lukewarm and brief, wear soft loose clothing, and keep fingernails short. Note when the itch began, where it is strongest, whether a rash comes and goes, and any new medicine, food, product, travel, or contact with someone itchy. Avoid scratching until skin breaks. A clinician may need to examine the skin and, when the skin looks normal but itching persists, consider causes beyond the surface.

Book an appointment for persistent, widespread, sleep-disrupting, or unexplained itching, especially when there is weight change, night sweats, yellowing skin, or a new medicine. Seek urgent care for itching with facial or tongue swelling, breathing difficulty, faintness, blistering, skin peeling, or a rapidly spreading rash.

Ask whether the distribution and skin findings fit eczema, contact reaction, infection, infestation, or another cause. Share your symptom diary and ask which treatments are safe with your medicines and conditions, and whether anyone else at home needs assessment.
