tinnitus

Tinnitus refers to the abnormal sound sensation produced by people without any external stimulus. If there are monotonous or mixed sounds such as cicada, buzz, hiss, and nourishment in the ear, there is no corresponding sound in the surrounding environment, which means that tinnitus is only a subjective feeling. Tinnitus can be transient or persistent. Severe tinnitus can disturb a person for a moment and make them nervous. If it is transient tinnitus, it is usually a physiological phenomenon, so don't be overly nervous, just let it go. If you have persistent tinnitus, especially with other symptoms such as deafness, dizziness, headache, etc., you should be alert and seek medical treatment as soon as possible.
