Itchy skin (pruritus) is usually from dryness, allergy or a skin condition. Persistent, whole-body itching without a rash can occasionally point to an internal cause.
Generalised itch without a rash can be dry skin, but persistent cases are sometimes linked to thyroid, liver, kidney or blood conditions and deserve blood tests.
Moisturise regularly, avoid hot showers and harsh soaps, and use antihistamines for allergic itch. See a doctor if it is severe, spreading or not settling.
