Nettle rash or hives (urticaria) are localized, pale, itchy, pink wheals (swellings) that can burn or sting. They may occur singularly or in groups on any part of the skin. Most episodes of hives disappear quickly in the space of a few days to a few weeks.

Why do I have symptoms?

Hives could be both allergic and non-allergic and is very common. Allergy is a more common cause of hives in children than in adults. Controlling food allergies has been shown to reduce symptoms.

In addition to allergy to foods or other substances like drugs, hives may be triggered by direct physical stimulation such as temperature extremes, water, sun, and physical exercise. Viral infections and stress can also cause an outbreak of hives. If you think you or your child has food allergies, an allergy test can help to specifically identify your food triggers. Do not try to manage the problem yourself by removing foods from the diet until you get a correct diagnosis.
