A left ear that feels like a drum may be the result of ear canal cerumen, otitis media, high blood pressure, and other conditions. It should be treated by cleaning ear canal cerumen, treating ear inflammation, lowering blood pressure, and adjusting lifestyle. 1. People with cerumen impaction: It can affect sound conduction, and the formation of a closed cavity between the impaction and the eardrum can lead to a drum-like sound in the left ear. It is recommended to go to the hospital and have the doctor clean the secretions in the ear canal under the observation of otoscope to restore the ear canal to be clear. 2. Ear inflammation: For example, when the left ear suffers from secretory otitis media, it will cause fluid accumulation in the ear cavity of the left ear, making the eustachian tube function decline, resulting in tinnitus. If it develops into a chronic condition, tympanotomy and tube placement can be chosen to relieve the symptoms. 3. High blood pressure: Patients with high blood pressure have higher pressure on the blood vessels in the left ear, which may result in a drum-like sound in the left ear. It is recommended that such patients, under the guidance of the doctor, actively control blood pressure to avoid the phenomenon of high and low blood pressure. Lifestyle adjustment: Lack of sleep, mental stress, excessive pressure, or wearing headphones in the left ear for a long period of time may cause abnormalities in the nerves of the left ear, resulting in a drum-like sound in the left ear. It is recommended that patients maintain a good state of mind, avoid excessive stress, avoid wearing headphones for too long, and ensure adequate rest. When the sound of the left ear like a drum, it is recommended that patients go to a regular hospital for examination and diagnosis, and take targeted standardized treatment.
