Itchy Skin

Itch without an obvious rash

This page is about the itch itself. If you can see welts, blisters or a patch, start with rash or allergic rash; if your skin is mostly rough and flaky, see dry skin. healthdirect advises seeing a doctor if you are very itchy and there is no rash. Itch over the whole body is often allergic, but it can also come from kidney or liver disease, an overactive or underactive thyroid, a blood disorder, or some medicines, recreational drugs and herbal supplements. Take a list of everything you use, including over-the-counter and herbal products. Severe itching during pregnancy, especially all-over itch that includes the palms and soles, also needs a doctor's check.

Breaking the itch–scratch cycle

Scratching makes skin itchier, so the cycle repeats, and broken skin can become infected or left with dark or pale marks. Keep nails short, wear loose cotton rather than wool, and swap soap or shower gel for a soap-free wash. A cool shower can give short-term relief; pat dry instead of rubbing, then moisturise while the skin is still damp. If the itch keeps you awake or keeps coming back, see your GP, or call healthdirect on 1800 022 222 at any hour.
