Urticaria (hives) is a common allergic skin reaction, usually mild but prone to recurrence. It mainly manifests as red or pale wheals on the skin, accompanied by itching, and usually subsides on its own within hours or days. Mild symptoms can be relieved with daily care; however, if accompanied by severe reactions such as difficulty breathing, immediate medical attention is necessary.
1. Common symptoms and triggers
Typical symptoms include the sudden appearance of wheals of varying sizes on the skin, accompanied by significant itching. These symptoms can be triggered by food, medications, pollen, or physical stimuli (such as heat, cold, or stress). Emotional fluctuations or fatigue can also induce them.
2. In most cases, it will resolve on its own.
Most attacks are localized and short-lived, and can be controlled by avoiding allergens, applying cold compresses, or taking antihistamines (such as loratadine), without affecting long-term health.
3. Serious situations requiring vigilance
A small number of patients may experience angioedema, manifested as swelling of the eyelids and lips; if accompanied by chest tightness, difficulty swallowing or breathing, it may indicate a systemic allergic reaction, requiring emergency treatment.
Daily advice: Record your diet and environment during flare-ups to help identify triggers; wear loose cotton clothing to avoid scratching; if symptoms become frequent or worsen, please consult a dermatologist promptly and use medication as directed by your doctor. Maintaining a regular sleep schedule and engaging in moderate exercise can help reduce recurrence.
