Buzzing and stuffiness in the right ear may be related to Meniere’s disease, secretory otitis media, cerumen impaction and other causes. 1. Meniere’s disease: When suffering from Meniere’s disease, recurrent episodes of vertigo may occur during the attack period. It is accompanied by tinnitus (e.g., buzzing), stuffiness in the ear, and hearing loss. 2. Secretory otitis media: After inflammation and infection, fluid collects in the middle ear cavity and the tympanic membrane is invaginated, resulting in negative pressure in the middle ear cavity, which leads to tinnitus, stuffy ears, hearing loss and other symptoms. 3. Cerumen embolism: When the external ear canal secretes too much cerumen and is not cleared in time, the external ear canal will be blocked, resulting in blockage of the ear. When the cerumen irritates the tympanic membrane inside the ear, it will lead to tinnitus, which is a buzzing sound in the ear. The buzzing and stuffiness in the right ear may be caused by other reasons, so it is recommended to go to the ear, nose and throat clinic as soon as possible to clarify the cause of the problem and standardize the treatment.
