- Insect stings. The allergic reaction to a sting from a bee or other insect causes local swelling, redness, and pain.
The severity of an allergic reaction’s symptoms can vary widely:
- Mild symptoms may be almost unnoticeable, just making you feel a little “off.”
- Moderate symptoms can make you feel ill, as if you’ve got a cold or even the flu.
- Severe allergic reactions are extremely uncomfortable, and incapacitating.
The most severe allergic reaction is called anaphylaxis. In anaphylaxis, allergens cause a whole-body allergic reaction that can include:
- Difficult/noisy breathing
- Swelling of the tongue
- Swelling or tightness in the throat
- Difficulty talking or hoarse voice
- Wheeze or persistent cough
- Persistent dizziness or collapse
- Pale and floppy (especially in young children)
Anaphylaxis is life-threatening and requires immediate medical attention. Symptoms can progress rapidly, so call 000 immediately if there’s any suspicion of anaphylaxis.
