Prolonged head-down playing with cell phones using computers can induce cervical spondylosis in addition to the increasing records of triggering otoliths. The action of prolonged head bowing affects the blood supply to the ear. As the body position changes, the otolith, which plays a balancing role, often leaves its normal tissue position and falls out into the semicircular canal of the inner ear. When the otolith changes with the body position, the person develops vertigo. If the dizziness is caused by a change of position and the duration of the dizziness is a few seconds to a dozen seconds, and the symptoms can be improved by changing the position of the head, it is likely that there is something wrong with the ear. If dizziness occurs, you should go to the hospital as soon as possible. After the examination and test in the regular hospital, the patient will be treated with the correct reset. Most patients can recover after one or several repositionings. There are many causes of vertigo, including otorhinolaryngology, neurology, orthopedics, psychology and other disciplines, but most hospitals do not have vertigo specialists, so patients often go to several departments to do a round of examinations and spend a lot of money to get effective treatment.
