Patients with ear pain after nasal washings may heal on their own, but if they have significant symptoms, it is recommended that they seek treatment from an ENT department as soon as possible. The ear pain after nose wash may be related to water flowing through the eustachian tube and entering the tympanic chamber retrogradely during the process of nose wash, inducing otitis media in the patient. If the amount of water is small and does not induce an obvious infection in the tympanic cavity, a small amount of water can be discharged through the eustachian tube on its own, and the ear pain may be relieved on its own after it is discharged. If the amount of water is relatively large and accompanied by an obvious infection in the middle ear cavity, this condition is difficult to heal on its own and requires a visit to the ENT department for nasal spray hormone application to promote the opening of the eustachian tube and pharyngeal opening. Patients can take oral antibiotics for anti-inflammatory treatment and oral mucus promoter-type drugs to promote the excretion of secretions in the tympanic chamber as soon as possible, thus facilitating the recovery of otitis media as soon as possible.
