Otitis media is difficult to heal on its own because it is caused by an acute bacterial infection that leads to reduced eustachian tube function, resulting in fluid accumulation in the middle ear cavity. Patients will experience sudden high fever, with body temperatures above 38.5°C, severe pain in the ear, and symptoms of hearing loss, tinnitus, and a feeling of ear fullness. Upon examination, the eardrum appears significantly congested and swollen, and a large amount of fluid can be found in the middle ear cavity. In terms of treatment, otitis media initially requires symptomatic anti-inflammatory treatment. Patients can take oral medications such as cefaclor, amoxicillin, and potassium penicillin V tablets. At the same time, the ear should be treated locally with ofloxacin ear drops twice a day, which can reduce local congestion and swelling. During treatment, patients also need to maintain a light diet, avoid vigorously blowing their nose, and prevent water from entering the outer ear canal. Generally, recovery can gradually occur within a week. (The use of medication should be under the guidance of a doctor.)
