Hot sun, swimming is a good choice for summer. Recently, after swimming, there are always people who have unilateral and bilateral ear stuffiness, blockage in the ear, can not hear the sound, and even pain in the ear, tinnitus, water in the ear canal. What’s going on? Ear, nose and throat experts explain: normal ear canal into the “S” shape curved, tube, long 2.0-2.5 cm. normal external auditory canal surface is covered with a thin layer of skin, the skin contains a wealth of sensory nerve endings, hair follicles, sebaceous glands and ceruminous glands. The yellowish-brown sticky material secreted by the ceruminous glands is called cerumen, commonly known as “earwax” or “earwax”. When the ear canal is not cleaned for a long period of time, the cerumen gathers and dries to form a lump that may block the external ear canal. There is no discomfort on weekdays when the ear canal is not completely blocked, but once the ear canal is flooded with water and the earwax is soaked for a long time, the ear canal will be completely blocked, affecting the functioning of the ear canal and the symptoms mentioned above will appear. Swimming is one of the main ways to get water in the ear canal. What about ear canal discomfort? It is recommended that you visit a specialist clinic as early as possible, and just perform ear canal cerumen removal. If there is a delay in consultation, acute inflammation of the external auditory canal, boils, eczema, and even fungal infections of the ear canal and acute otitis media can occur over time. So remember to seek early medical attention.
