It may be a symptom of certain diseases, such as cerumen impaction, secretory otitis media and sudden deafness. 1. Cerumen impaction: When cerumen glands secrete more cerumen, especially oily cerumen, it is not easy to be discharged, and the long-term accumulation of cerumen blocks the ear canal and tympanic membrane, which can lead to a sense of blockage and congestion in the ear, sometimes accompanied by hearing loss and tinnitus, etc. Generally speaking, the sense of congestion in the ear will be cured after removing the cerumen. 2. Secretory otitis media: due to inflammation in the middle ear or abnormal function of the eustachian tube, resulting in the tympanic membrane invagination, which can cause ear stuffiness, low-pitched tinnitus, hearing loss and other symptoms. 3. Sudden deafness: it may be due to the inner ear circulatory dysfunction or the membrane labyrinth accumulation of water, sudden low-frequency sensorineural hearing loss, and ear stuffiness. Therefore, when there is ear stuffiness, you need to consult a doctor in time to clarify the cause of the disease and target treatment.
