Patient: Description (onset time, main symptoms, hospital visited, etc.): I am a patient of Dr. Wen, I have been treated quite well, and I have found in the last two days that my son (seven years old) has similar symptoms to mine: nasal congestion, itchy nose, runny nose, sneezing in the early morning, itchy eyes with redness and swelling in severe cases, sometimes coughing I would like to ask the doctor how to prevent it? What things should I pay attention to during my child’s checkup? Wen Liping: If there is no examination, only symptomatic treatment can be given, that is, treatment for symptoms. It is recommended to use nasal sprays and anti-allergy medication under the guidance of the local doctor. For children to be checked, they generally have to be over 3 years old. —- Because of the skin test/blood draw, it may not be possible to check at too young an age. Your child is 7 years old and can be tested accordingly. See if allergens play an important role in the onset of the disease. Desensitization, on the other hand, generally has to be started at age 5 or older.
