Hello: If the secretion in the nasal cavity is habitually inhaled, it will cough up from the throat, which is the symptom you mentioned. This habit for a long time will stimulate the inflammatory reaction in the throat, thus causing the possibility of chronic pharyngitis.
Guiding opinions:
In this case, it is still considered that rhinitis is possible, and not all rhinitis has symptoms of allergic reaction.
It can be considered to use drugs to promote the absorption of nasal inflammatory exudation. In addition, nasal drops are used, preferably nasal secretions are discharged from the front nostril.
