It always occurs in a specific position and presents a rigid attack, such as lying up in bed, turning left and right in bed, or bending up, Or when you turn your head, it may cause the patient to have a vertigo attack, and the duration is very short, usually a few seconds, not more than 1 minute. The degree of dizziness can be serious, such as the sense of spinning or horizontal shaking. Some patients can also be accompanied by nausea, vomiting and other symptoms. Because the head position does not change when walking, dizziness can not occur. This disease can be treated in the hospital by manual repositioning under the guidance of a specialist doctor. In addition, it is suggested that the patient should also go to the hospital in time to make a clear diagnosis and exclude other diagnoses. When necessary, it is also necessary to improve the examination to find out the cause of dizziness, and find out whether it is because of other diseases that the patient has vertigo attacks, Then proceed to the next step of treatment.
