Buzzing in the head is also called tinnitus, which is considered to be caused by physiological factors, cerebrovascular disease and intracranial tumors, etc. Patients need to be treated accordingly. 1. Physiological factors: Tinnitus may occur due to lack of sleep, overwork or mental stress. This is a normal physiological phenomenon, which can be improved by resting and keeping a happy mood. 2. Cerebrovascular disease: If the patient has insufficient blood supply of cerebral arteries, cerebral infarction and cerebral arteriosclerosis, etc., which affects the patient’s auditory nerves and causes tinnitus, it is recommended that the patient go to the hospital in time for treatment according to his own condition. 3. Intracranial tumors: If patients develop diseases such as acoustic neuroma and glioma, which compress the auditory nerve, tinnitus may occur. In addition to tinnitus, it can also be accompanied by unsteady walking, dizziness or headache and other symptoms. If the tinnitus persists and cannot be relieved, it is recommended to go to the hospital in time.
