Urticaria (hives) is an allergic reaction of the skin to certain stimuli, manifesting as red or skin-colored wheals, often accompanied by itching. If you experience similar symptoms, it is recommended that you observe and record possible triggers, and consult a doctor if necessary.
Specific symptoms and common causes include:
1. Typical symptoms: The skin suddenly develops raised wheals of varying sizes, similar to mosquito bites, with clear borders. They may subside within hours but recur.
2. Common triggers: Food (such as seafood and nuts), medications, environmental factors such as pollen, and physical stimuli (such as friction and changes in temperature) can all trigger it.
3. Characteristics of the onset: Itching is obvious, and a few people may experience local swelling, but it usually does not leave scars for a long time.
The following aspects can be noted in daily life:
Record any food or environmental changes encountered before an attack to help identify the trigger; wear loose cotton clothing to avoid scratching; if symptoms persist or are accompanied by severe conditions such as difficulty breathing, seek medical attention promptly. With proper observation and protection, most cases can be effectively relieved.
