Foreign body sensation inside the nose does not necessarily mean cancer. In life, if a patient suddenly has a foreign body sensation in the nose, he or she can go to the hospital for detailed examination to clarify whether there is indeed a foreign body in the nose. If there is, the diagnosis can be confirmed by nasal endoscopy or CT of the nose, and if a foreign body is found, the foreign body can be removed under the nasal endoscope. Sometimes patients feel that there is always a discharge or a foreign body in the nasal cavity because of the enlarged turbinates, and the nasal mucus is particularly sticky in hypertrophic rhinitis, and it is not easy to blow the nose after blowing it hard. Patients can take eucalyptus pinene enteric soft capsule orally to promote the discharge of nasal snot out of the nasal cavity; at the same time, they can also spray with trimethoprim nasal spray and take nasal abdomen and orthodontic granules together to reduce the symptoms of foreign body sensation in the nasal cavity.
