I want to find out what the cause is. Hope to take the road less traveled! Zhi Yu Xiang: Allergies are one of the major causes of runny nose, sneezing, itchy eyes and asthma. If you want to clarify whether it is caused by allergies, please go to the allergy department of the hospital and remind you to stop taking antihistamines (anti-allergy drugs) three days before your visit. Do not take anti-cold medication either. Inhalation preparations for asthma do not need to be stopped.
