For urticaria, you can consult a dermatologist. If the hospital has more specialized departments, you can also choose the allergy or hypersensitivity department within the dermatology department. The following are specific instructions:

1. Dermatology is the first choice: Urticaria mainly manifests as wheals and itching on the skin, and is a common skin problem. Dermatologists can directly diagnose the type of rash and prescribe medication to relieve symptoms.

2. Consider consulting an allergy specialist: If symptoms are recurrent and you suspect they are related to food, pollen, or other allergies, consult a hospital with an "Allergy Department." These departments will help identify potential triggers through testing.
3. Special circumstances: Some patients may experience severe chest tightness or difficulty breathing, requiring immediate emergency medical attention; if the rash is clearly related to the medication, consult the prescribing department or dermatology department.
It is recommended to briefly record the time of rash appearance, changes in appearance, and any possible foods or medications that may have been in contact with the skin before your visit. This can provide useful clues for the doctor's diagnosis. In daily life, wear loose-fitting cotton clothing and avoid excessive scratching of the skin.
