The main symptom of hives is an itchy rash.

The rash can:

• be raised bumps or patches in many shapes and sizes
• appear anywhere on the body
• be on 1 area or spread across the body
• feel itchy, sting or burn
• look pink or red when affecting someone with white skin; the colour of the rash can be harder to see on brown and black skin

You get hives when something causes high levels of histamine and other chemicals to be released in your skin. This is known as a trigger.

Triggers can include:

• eating certain foods
• contact with certain plants, animals, chemicals and latex
• cold, such as cold water or wind
• hot, sweaty skin from exercise, emotional stress or eating spicy food
• a reaction to a medicine, insect bite or sting
• scratching or pressing on your skin, such as wearing itchy or tight clothing
• an infection
• a problem with your immune system
• water or sunlight, but this is rare

Try to find out what triggers hives for you, so you can avoid those triggers, if possible. This may help prevent an episode of hives.
