Nose aspiration and headache, patients are advised to go to a rhinology clinic for nasal endoscopy and, if necessary, sinus CT to confirm the diagnosis. Dry rhinitis and atrophic rhinitis are common in clinical practice. In patients with rhinitis, the nasal mucosa is particularly dry, the mucosa is atrophic, and the nasal cavity may be hyperventilated, making the function of nasal insulation and moisture retention particularly poor. If the patient suddenly inhales a large amount of air, especially a large amount of cold air inhalation stimulation, a headache may occur. In addition, because of the poor function of the nasal mucosa, patients like this tend to have a large amount of nasal crust blockage in the nasal cavity. With nasal crust blockage and pressure on the nasal mucosa, nasal pain may also occur, and patients are advised to apply saline for nasal rinsing under the guidance of an outpatient doctor, which can rinse out the nasal crust and also keep the nasal cavity moist, which has a restorative effect on the state of the nasal cavity. You can also use compound menthol nasal drops for nose drops, and you can also use recombinant bovine basic fibroblast factor gel to apply to the nasal cavity, which can promote the recovery of mucosal epithelium and keep the nasal cavity moist with very good effect.
