Itch (pruritus) has many possible causes, including dry skin, eczema, psoriasis, allergic reactions, and sometimes internal conditions. Self-care can help while you identify the cause.

Helpful steps

See a doctor if: itch is severe, widespread, lasts more than a couple of weeks, comes with a rash that is spreading, or is accompanied by other symptoms such as weight loss or fatigue.
Disclaimer: These are general comfort measures only. Persistent itch needs professional evaluation.
