There are many causes of dizziness. If most of the dizziness occurs when the head is turned, it is important to consider whether the patient has cervical disc herniation or cervical spondylosis, and an MRI of the cervical spine can be performed to determine whether the patient has a combination of cervical disc herniation, spinal stenosis, and insufficient blood supply to the basilar artery caused by compression of the vertebral artery when the head is turned, leading to dizziness. In addition, an otolaryngology examination should be performed to determine whether the dizziness is caused by obstruction of lymphatic drainage in the inner ear or otoliths, which irritate the semicircular canal. Dizziness caused by otoliths is benign positional vertigo, which can be repositioned by manipulation, and the symptoms of dizziness will be relieved significantly in a short period of time after repositioning.
