What should you know about uncontrollable itching all over body?

Itching may arise from dry or irritated skin, an allergy, infection, a medicine, or a condition affecting the liver, kidneys, thyroid, nerves, or blood. Some people itch even when the skin looks normal. Scratching can break the skin and create a route for infection.

Generalised itching can occur with some blood cancers, including Hodgkin lymphoma, but itching alone does not identify its cause. A clinician may ask about timing, sleep, new products, medicines, weight change, fevers, night sweats, lumps, and skin changes. Examination and selected blood tests can help direct the next step. Vulvar itching has a separate range of causes and deserves a focused examination when it persists.

Use lukewarm rather than hot water, a gentle unperfumed cleanser, and a plain moisturiser after washing. Wear loose breathable clothing, keep nails short, and use a cool cloth instead of vigorous scratching. Avoid starting a new cream, supplement, or antihistamine without checking that it is suitable with your medicines and health conditions.

Arrange a medical assessment if itching continues, disrupts sleep, spreads, or has no clear trigger. Note where it occurs, whether a rash appears, and any new medicines or products. Take photographs of changing skin areas and bring a medicine list. Persistent vulvar symptoms should be assessed rather than treated repeatedly at home.

Seek urgent help for itching with swelling of the lips or tongue, breathing difficulty, faintness, or a rapidly spreading blistering rash. Contact a clinician promptly for fever, drenching night sweats, unexplained weight loss, a new lump, yellow skin, dark urine, severe weakness, or skin that is painful, broken, or infected. These warning features guide urgency; they do not prove that cancer is present.

Ask what causes are most relevant to your symptoms, whether your medicines or liver and kidney function need review, and whether blood tests or a skin examination are appropriate. Ask how to protect scratched skin, which treatments are safe for you, and what changes should trigger earlier review. If symptoms are centred on the vulva, ask whether a specialist assessment is needed for [Vulvar Cancer](/conditions/vulvar-cancer/).
