The feeling of a foreign body in the ear that rings when you move it may be caused by the presence of a foreign body in the ear, excessive cerumen, otitis externa and other factors. 1. Foreign body in the ear: when taking a bath or doing some outdoor activities, water and other foreign bodies enter into the ear, you will feel that there is a foreign body in the ear, and there is a ringing sound when you are moving around, and there is an obvious sense of rolling of the foreign body. 2. Excessive cerumen: If you don’t pay attention to the cleaning of the ear in your daily life, and the secretion in the ear is close to the tympanic membrane too much, cerumen clumps may be formed, and you will feel that there is something in your ear when you are chewing, swallowing, or moving around, and a ringing sound will appear when you are shaking your head. 3. Otitis externa: When otitis externa exists, the infection continues to worsen, and a lot of pus is secreted, which mixes with the dander inside the ear, leading to a foreign body in the ear as well as a ringing sound, accompanied by pain, foul-smelling secretions and other symptoms.
