Cervical vertigo occurs when the vertebral arteries or sympathetic nerves are stimulated, resulting in a sudden, short-lived dizziness that usually lasts 3-5 seconds. How to prevent it? First, maintain proper living and working habits. Avoid prolonged bowing of the head, sedentary, sitting for more than 30 minutes to get up and move, or the neck to do backward stretching exercise. If the vertigo is heavy, you need to wear a neck brace to enclose your neck and avoid excessive neck movement. Localized neck massage, medium frequency, electro-acupuncture and other therapeutic measures can be done, and non-steroidal drugs such as Fitalin can also be used. Cervical vertigo attacks are more frequent you need to go to the hospital for formal examination and treatment.
