Diving earache can be treated by applying nasal mucosal decongestants, oral antibiotics, oral mucus promoters, and puncture aspiration. If the condition is mild, it can be relieved on its own in a relatively short period of time. If the ear pain is obvious and accompanied by a feeling of ear stuffiness and congestion, it is necessary to consult a doctor as soon as possible to determine the severity of the condition. Nasal mucosal decongestants such as ephedrine nasal spray can be applied to promote the opening of the pharyngeal opening of the Eustachian tube. Eustachian tube blowing can be combined with other methods to promote the opening of the Eustachian tube to restore the balance of air pressure inside and outside the middle ear drum. If fluid builds up in the tympanic cavity, oral mucolytic agents, such as eucalyptus-pinocampus enteric capsules, can be taken, along with oral antibiotics, such as amoxicillin, to prevent bacterial infections. If the condition is more serious and drug treatment is not effective, tympanocentesis can be used to extract fluid. It is recommended that patients consult a doctor in time to check their condition, and all the above drugs need to be treated under the guidance of a doctor.
