There are many causes of earache, such as otitis externa, otitis media, cerumen impaction, etc., which need to be treated with anti-infection and cerumen softening according to the cause. 1. Otitis externa: it is often manifested as swelling and pain in the ear. In this case, the external ear canal should be cleaned, and antibiotics can be used locally to control the infection, such as levofloxacin ear drops, or oral antibiotics, such as erythromycin and cefuroxime. 2. Otitis media: Otitis media often presents symptoms of ear pain, ear stuffiness and ear blockage. This condition can be treated with oral antibiotics such as erythromycin, cefuroxime and cefazoxime. At the same time, antibiotic ear drops (such as ofloxacin ear drops) can play a role in relieving pain and swelling. 3. Cerumen embolism: Cerumen is earwax. When cerumen gathers in large quantities and forms a mass, it will block the external ear canal, resulting in hearing loss, tinnitus, earache and other symptoms. In this case, you can use 5%-10% sodium bicarbonate solution as ear drops first, and then clean out the cerumen after it softens. There may be other causes of earache, such as boils in the external auditory canal, acute tympanitis, and middle ear occupancy. It is recommended to consult a doctor in time to identify the cause and then target treatment. The above medications should be used under medical supervision.
