The key symptom of hives is a rash, which is usually uncomfortable, causing itching, burning or stinging.

The rash may cover one area of the body, or the whole body; it may be raised; on people with white or pale skin the rash may be pink.

Hives is caused by your immune system releasing histamine in response to something it identifies as foreign.

They’re usually caused by eating a particular food; coming into contact with a certain material, plant, animal or chemical; medicines; insect bites or stings; sensations like cold, hot or scratching; stress; sweat; an immune problem.

Toxins and viruses may also cause hives.
