The ABC symptoms will usually (but not always) also come with other less-serious symptoms:
- Widespread flushing of the skin.
- Rash.
- Swelling of the skin anywhere on the body (for example, lips, face).
- Stomach pain, feeling sick and vomiting.
If the person doesn’t have any of the key ABC symptoms, the allergic reaction is probably less serious. But even then, you should watch carefully in case ABC symptoms develop.
To be prepared and to help you and those around you know what to do in an emergency, it’s important to have an allergy action plan.
