There are many reasons for the rustling sound inside one side of the ear, such as cerumen in the external ear canal, foreign body, otitis media, etc.
1. Cerumen in the external auditory canal: commonly known as earwax, it is a yellowish substance secreted by the cerumen glands in the external auditory canal, which is in the form of thin flakes after drying and is often found in the external auditory canal, causing friction when chewing, shaking the head, and so on, resulting in a rasping sound in the ear.
2. Foreign bodies: When substances such as hair and insects enter the external ear canal, rustling sounds will also occur inside the ear.
3. Otitis media: Due to inflammatory secretions and inflammatory factors stimulating blood vessels and nerves inside the ear, abnormal rustling sounds may also occur.
In addition to the above reasons, it may also be caused by tinnitus, sudden deafness and other reasons. Therefore, if the above symptoms occur, it is recommended to go to the ENT department of the hospital in time for early and regular treatment.
