What are the causes of sudden onset of deafness? What are the symptoms?

  Modern city life is always full of busy pace, fast-paced life and stress make many people in sub-health. Most people who suffer from sudden deafness often stay up late, work under stress and are chronically fatigued. As a result of long-term stress and physical and mental overwork, the blood supply to the inner ear is hindered, which can easily lead to deafness once stimulated by the outside world. The overload of work pressure can also worsen the condition of people suffering from tinnitus. Many patients with sudden deafness will have different degrees of vertigo, tinnitus, vomiting and other symptoms at the beginning of the disease, which are obvious signs of sudden deafness, but are easily ignored.  Sudden deafness is an emergency and the treatment effect is proportional to the time of onset, which generally cannot exceed 3 days. If treatment has been delayed, it can cause serious damage to hearing, and in severe cases, hearing loss may occur within a few days, or even hearing loss, resulting in deafness. Since the age of 20 to 40 is the high incidence of sudden deafness, young white-collar workers should pay high attention to it. Once they suffer from deafness, they should go to a professional hospital in time for active treatment.
