Nettle rash (acute urticaria)

goodtoknow says: Nettle rash is an allergic skin rash, also called urticaria or hives. Acute Urticaria appears suddenly and lasts for around two days. The rash looks like large, raised slightly inflamed areas of skin which are called 'wheals' and are very itchy. Common triggers for acute urticaria include food allergies, insect bites and nettle stings, cosmetics, rubber latex and chemicals. The rash isn't serious and antihistamines will ease the discomfort. So will a cool bath. Your child should feel otherwise well but if you can work out what triggered the rash, it would be sensible to avoid it in future.

Acute urticaria is a condition where an itchy rash suddenly develops. The rash may be triggered by an allergy, or by another factor such as heat or exercise. In most cases the rash lasts 24-48 hours and is not serious. You may not require any treatment, but antihistamines can ease the symptoms until the rash clears.
