If the eardrum is simply congested, it is not serious, because water or loud sound stimulation in the ear, as well as pulling out the ear too deeply can cause the eardrum to become congested, and if it is not accompanied by other symptoms, no further treatment is necessary. However, if there are other symptoms, such as ear pain, swelling and stuffiness, or hearing loss in the ear, then further treatment is needed and otitis media is likely to develop. When you have otitis media, you can consider using medications for otitis media, such as anti-inflammatory drugs like cephalosporin or azithromycin, and medications to promote the opening of the eustachian tube, such as Ceno or Genoton, etc. If the eardrum is obviously congested, you can also use ear drops, such as oxyfloxacin ear drops or levofloxacin ear drops to treat it. It is important to note that if tympanic membrane lighthouse disease occurs, that is, if the tympanic membrane is found to be flickering under the mirror, there may be fluid accumulation in the middle ear cavity, which may cause tympanic membrane perforation, and if the ears appear to be thick and dripping, further treatment should be given in the hospital.
