Urticaria is usually triggered by a variety of factors such as allergic reactions, infections, or physical irritants, and the specific cause varies from person to person. If it recurs frequently, it is recommended to keep a record of everyday contacts and consult a doctor.
1. Allergens: Foods such as seafood and nuts, or medications and pollen may trigger an overreaction in the body, leading to hives and itching on the skin.
2. Effects of infection: Infections such as colds and toothaches may disrupt the immune system and indirectly trigger skin symptoms.
3. Physical stimuli: External stimuli such as friction, pressure, temperature changes, or sun exposure can also directly cause skin reactions.
4. Other triggers: Emotional stress, fatigue, or certain chronic diseases may make symptoms more likely to occur.
In daily life, avoid known triggers, wear loose clothing to reduce skin friction. During an flare-up, avoid scratching; apply cold compresses to relieve itching, and seek medical attention promptly to determine the cause and use medication as directed by a doctor to control symptoms.
