What should I do if I can't hear clearly and feel blocked?

"Some time ago, due to the uncertain weather, I was cold and hot, and I always caught a cold. Intermittent treatment for more than a month. Last week, I began to find that I couldn't hear clearly, and it was as uncomfortable as something blocking it. What is the reason? What should I do? " -Miss Fang from Wuhan, Hubei Province consulted Wuhan Ren 'an Hospital online. Answer: I can't hear clearly, and I feel blocked. I think it's otitis media caused by a cold. It is recommended to go to the otolaryngology department for examination and treatment as soon as possible. There is a thin tube leading to the nasopharynx in the middle ear cavity, which is medically called eustachian tube. Normally, there is air in the middle ear. On the one hand, this air is constantly absorbed by the mucosa of the middle ear, on the other hand, new air is input through the eustachian tube, which makes the middle ear cavity equal to the external air pressure, thus maintaining the vibration of the tympanic membrane and ensuring the normal hearing function. When you catch a cold, it will prevent air from entering the middle ear through the eustachian tube, which will cause otitis media. What is the best treatment for otitis media? Thoroughly treating otitis media with "otomicroscope technology +CZT-8F audio * * vibration system" Wuhan Ren 'an Eye Otolaryngology Hospital used otomicroscope technology combined with CZT-8F audio * * vibration system to treat otitis media, which won the trust of the majority of patients because of its good therapeutic effect. CZT-8F audio * * * vibration system is the first synchronous physiotherapy equipment with dual functions of computer-modulated intermediate frequency and computer ultrasound in the world, and it has obtained the national invention patent. First, (otoscope) imported otoscope carefully examines ear lesions, and one of the keys to ensure the safety of surgery is to fully expose the surgical field of vision. (2) (High treatment accuracy) Using the ear microscope to locate the lesions in the deep and hidden parts of the ear can effectively reduce the difficulty and risk of treatment and improve the treatment accuracy. (Pure physical therapy is safe and efficient) The therapeutic mechanism of computer-controlled three-dimensional superimposed vibration formed by ultrasound and low-and medium-frequency biological electromagnetic waves is that natural physical factors such as sound, frequency, heat, electricity, magnetism and micro-massage penetrate into the focus synchronously, forming a three-dimensional effect of audio vibration and physical and chemical superposition. Combined with drug penetration, music therapy, acupoint guidance and other therapeutic factors, it can accelerate blood circulation, eliminate inflammation, improve hearing and achieve the purpose of curing otitis media and otitis externa. Tips: In the late stage of a cold, once you have symptoms such as nasal congestion, headache and earache, you should go to the otolaryngology department in time. There are also many colds and runny noses. It is more dangerous to blow your nose too hard, which will bring viruses and bacteria into your ears through the eustachian tube and cause middle ear infection. Everyone should pay more attention.
