What are nettle stings?

Nettle stings can be itchy and you may feel a stinging or burning sensation. This will usually settle down within a few minutes or a few days and you can often treat them yourself. They may cause a raised area nettle rash on the skin.

Signs and symptoms

Look for:

  • a stinging sensation

  • white or red spots

  • red, raised patches.

What to do

  1. 1

    Wash the affected area with soap and water as soon as possible.

  2. 2

    Avoid scratching or rubbing the itchy area.

  3. 3

    The discomfort should improve within a couple of hours. Seek medical assistance if it continues.

    • If the casualty is known to be allergic to nettle stings, they may have their own medication, such as an auto-injector.

    • If the irritation is severe, cooling the skin with a damp cloth or ice pack (or a pack of frozen vegetables wrapped in a tea towel) may be helpful.

    • A pharmacist will be able to advise regarding the use of antihistamines and creams to relieve the irritation.

    • In very rare cases, an individual may have a severe allergic reaction to a nettle sting. If this happens, treat for anaphylaxis and seek urgent medical help.
