Chronic rhinitis is caused by recurrent acute rhinitis or prolonged unresolved nasal symptoms. Patients may experience bilateral nasal congestion, which alternates in severity; the congestion is usually less during physical activity during the day and more severe when resting at night. Additionally, the nasal cavity may produce mucous secretions, and when accompanied by bacterial infection, yellow secretions may appear. Patients may also experience headaches, dry mouth, and decreased memory among other related symptoms. During examination, congested and swollen nasal turbinates on both sides are evident, and the effectiveness of ephedrine in causing constriction is good. In treatment, patients can initially use nebulized inhalation to constrict the nasal turbinates and reduce nasal congestion. Regular physical exercise is also needed to restore the function of the nasal mucosa, leading to gradual improvement. If conservative treatment is ineffective, local surgical removal may be required for recovery. (Medication use must be conducted under the guidance of a doctor.)
