Dizziness can be caused by a variety of diseases, such as poor sleep and rest, overexertion, inadequate blood supply, cerebral infarction, otoliths, or vestibular abnormalities. If there is no problem, there is no need to worry too much about any remaining causes of dizziness, and symptomatic treatment is sufficient. If there is no problem, the patient can also be given a postural evocation test to clarify whether there is otolithiasis, and if it is otolithiasis, further manual repositioning should be given. If the cause of dizziness is still not clear after the above comprehensive examination, bed rest, avoid strenuous activities, and oral treatment with flunarizine hydrochloride capsules are required, and the symptoms will usually disappear in a week or so.
