Motion sickness is mainly seen in the following cases: 1. Motion sickness, which is not very common, is mostly seen in people who sit in cars, but not in people who drive. Of course, this is related to the patient’s vestibular function, and some patients with poor vestibular balance may experience motion sickness due to changes in the direction of car acceleration and deceleration during driving. 2. 4. Patients may experience dizziness during driving due to long-term fixation of the neck in one posture or cervical spondylosis induced by local nerve compression, which may lead to dizziness. Of course, other conditions cannot be ruled out, such as hypotension or plant nerve dysfunction in some patients, and poor sleep and rest for a long time can also lead to dizziness during driving.
