1. Otitis media Among the ear diseases, otitis media should be familiar to people, and there are many reports warning that otitis media, if not treated in time, may cause the ear to lose its most basic function, which is deafness, and that otitis media is the number one killer of ear disability. The causes of otitis media are many, including acute purulent inflammation of the mucous membrane of the middle ear, a large number of viruses and bacteria in the nasal mucosa, and when forced by pressure, the nasal mucus will be forced out of the posterior nostril and reach the eustachian tube, triggering otitis media, as well as many other causes. 2. Congestion of the skin of the external ear canal Our ears allow us to hear all kinds of wonderful sounds in the world, incorporating so many sounds that our ears should be relatively strong, but our ears are so fragile, especially the external ear canal, which is often infected with bacteria causing congestion of the external ear canal, and the chronic congestion of the skin of the external ear canal for a long time will stimulate the cerumen gland to secrete earwax, which will gradually The earwax will gradually increase. If the amount of earwax in the external ear canal increases, the color is often brown, some are hard and some are soft, and the wall of the external ear canal is close to each other, and it slowly gathers into a mass, which will block the entire external ear canal for a long time, accompanied by symptoms such as stuffy ears, tinnitus, vertigo and hearing loss. This can lead to the blockage of the outer ear canal for a long time, accompanied by symptoms such as stuffy ears, tinnitus, vertigo and hearing loss. If water enters the ear during bathing, the ear canal will swell after soaking and the blockage will become more serious, which will increase the probability of cerumen embolism. The earwax embolism will not only cause inflammation and pain in the ear, but in serious cases, it will also make the skin of the external ear canal appear erosion and other undesirable symptoms. 4, throat disease It is said that toothache is not a disease, but a pain that kills, because toothache is accompanied by inflammation of the gums, and in serious cases, swelling will occur, and this time the pain will directly affect our ears, especially the ear root area will also have symptoms of inflammation, not only inflammation of the gums, and many other diseases. For example, inflammation of the tonsils, acute laryngitis, bronchitis, etc., can cause itching or pain in the ears, and can also increase ear wax. If such symptoms occur, don’t worry too much, because when the symptoms of throat disease heal and the inflammation disappears, the symptoms of ear wax will also disappear.
