Chronic rhinitis is usually characterized by varying degrees of nasal congestion, runny nose, and decreased sense of smell. Chronic rhinitis is usually divided into chronic simple rhinitis and chronic hypertrophic rhinitis. 1. Patients with chronic simple rhinitis may experience intermittent and alternating nasal congestion, which may be alleviated during exercise and aggravated at night when sitting still. When lying on the side, the lower side of the nasal cavity is blocked, the upper side of the nasal cavity is well ventilated, when turning to the other side of the lying position, the other side of the nasal cavity and nasal congestion. Nasal mucus may flow into the throat through the posterior nostril, causing throat discomfort, phlegm and coughing, and there may also be intermittent loss of smell, headache and nasal sound when speaking and other symptoms. 2. Chronic hypertrophic rhinitis is mostly persistent, with heavy nasal congestion, occlusive nasal sound, decreased sense of smell, and nasal mucus that is not easy to blow out. If the posterior end of the enlarged inferior turbinate presses on the pharyngeal opening of the Eustachian tube, tinnitus and hearing loss can also occur, accompanied by headache, dizziness, insomnia and mental depression and other symptoms. It is recommended that when patients suspect chronic rhinitis, they should go to the hospital in time to do the relevant examination, and under the guidance of the doctor reasonable treatment.
