Urticaria is a common allergic skin reaction, usually manifesting as red or skin-colored wheals accompanied by itching. In most cases, it does not cause serious harm, but it can affect quality of life. It is recommended to identify the triggers promptly and consult a doctor.

Specific symptoms and precautions include:

1. **Symptom characteristics:** Wheals often appear suddenly, vary in shape and size, and are intensely itchy. They usually subside on their own within 24 hours, but may recur.
2. **Common triggers:** These may be related to factors such as food, medication, infection, temperature changes, or stress. The triggers may vary from person to person.
3. **Potential Risks**: In rare cases, if accompanied by symptoms such as difficulty breathing or dizziness, a severe allergic reaction should be suspected, and immediate medical attention should be sought.
Daily advice includes keeping a record of your diet and environment during flare-ups to avoid known triggers; apply cold compresses to relieve itching and avoid scratching. If symptoms are frequent or worsen, consult a dermatologist for evaluation and to develop a suitable management plan.
