Rhinitis may cause a foreign body sensation in the throat. Foreign body sensation in the throat may be caused when nasal mucus flows backward into the throat and adheres there, or when breathing with the mouth open causes dryness and thickening of the mucous membrane in the throat. Patients often experience inflammatory reactions in the nasal cavity due to viral infections, bacterial infections, and allergic reactions. Patients often have nasal congestion, runny nose, decreased sense of smell, headache and other manifestations. When combined with bacterial infection, the secretion is mostly mucopurulent, which may lead to foreign body sensation in the throat when it flows backward to the pharynx and partially adheres to the mucous membrane of the pharynx, or when the nasal congestion and prolonged open-mouth breathing cause the local mucous membrane to be dry and thickened. In addition to rhinitis, sinusitis, pharyngitis, epiglottitis, etc. may cause foreign body sensation in the throat, it is recommended to consult a hospital as soon as possible when foreign body sensation in the throat occurs, so that the professional doctor will be diagnosed and treated.
