Sudden buzzing in the ear refers to sudden tinnitus, most commonly neurological tinnitus, which may be related to insufficient blood supply to the inner ear and poor microcirculation in the inner ear induced by the patient’s staying up late with fire and poor rest. For this kind of tinnitus, the following treatment can be done: 1. It is recommended that the patient go to the ENT clinic to improve the electronic tympanic membrane image, pure tone hearing threshold, acoustic conductance resistance and other examinations to exclude other diseases induced by tinnitus, and if neurological tinnitus is considered, medication can be applied. 2. If necessary, hormones, acupuncture, hyperbaric oxygen and other comprehensive treatments should be applied. For neurological tinnitus, treatment is effective in some patients and ineffective in others. During the treatment process, patients are advised to maintain a stable state of mind and avoid bad emotions such as anxiety, staying up late, fire, bull’s-eye, and knowledge of dead reason.
