The old feeling of cicadas in the ear belongs to tinnitus, which may be caused by ear diseases, hypertension, autonomic dysfunction and so on. 1. Ear diseases: Otitis media, mastoiditis, Meniere’s disease and other ear diseases can cause tinnitus, headache and other symptoms. 2. High blood pressure: patients with high blood pressure will have palpitations, tinnitus, dizziness, blurred vision and other symptoms due to the long-term higher than normal pressure on the walls of blood vessels. 3. Autonomic dysfunction: some people suffer from tinnitus, dizziness, and lack of concentration due to autonomic dysfunction caused by high stress in life and study and insufficient sleep. Patients with this symptom should consult a doctor in time to clarify the cause of the disease and then carry out appropriate treatment.
