Urticaria is mainly caused by allergic reactions or bodily sensitivity, and can be relieved through medication and daily protection. It is recommended to promptly identify the triggers and follow medical advice for treatment.

1. Common triggers include allergens such as food (e.g., seafood, nuts), medications, pollen, and dust mites. Physical stimuli (e.g., heat, cold, friction), infections, or stress may also trigger allergies.

2. During an acute attack, doctors often prescribe antihistamines to help relieve itching and swelling; if the attacks are recurrent, it is necessary to identify the allergen and avoid contact with it.
3. Daily diet and environmental changes can be recorded, loose cotton clothing should be worn, excessively hot baths should be avoided, and a relaxed mood should be maintained to reduce the occurrence of attacks.
If the rash persists or is accompanied by difficulty breathing, please seek medical attention immediately. Regularly observing your own reactions, cautiously trying new foods or products, and gradually adjusting your lifestyle will help with long-term management.
