If a bug accidentally enters into the nasal cavity, it needs to be taken out in time, which can be discharged by sneezing and blowing the nose, and taken out under nasal endoscopy. 1. Sneezing and blowing the nose: when a foreign body enters the nasal cavity, it can stimulate the nerve reflexes of the nasal mucosa, leading to sneezing symptoms, which is conducive to discharging the foreign body. Or by blowing your nose, you can increase the airflow in the nasal cavity, which is also conducive to the expulsion of the foreign body. 3. Nasal endoscopy: If the above methods cannot solve the problem, it may be due to the large size of the bugs or enter too deep, which is not good to be discharged. In this case, it is better to go to the otorhinolaryngology department of the hospital and take out the bugs with the assistance of nasal endoscopy. If the bugs are sucked into the nose and cannot be solved by yourself, it is recommended to go to the hospital in time.
