If you are still dizzy a few days after motion sickness, you should look for the cause. Most patients get dizzy when they get motion sickness, but the symptoms will be relieved the next day after the motion sickness. Dizziness can be caused by a variety of factors, such as elevated blood pressure or lowered blood pressure. Dizziness may also be caused by cervical spondylosis, which is mostly caused by insufficient blood supply to the basilar artery system, and can be treated with neck muscle massage and traction, as well as medications to improve blood circulation, such as blood transfusion, vincristine and chuanxiongzin, or blood sparing, cipro, etc. It may also be caused by intracranial organic lesions, mainly cerebrovascular diseases or cranial tumors, and if necessary, cranial MRI can be performed to clarify the diagnosis.
