Many patients in the outpatient clinic will complain of dizziness, and in fact many people who see dizziness in orthopedics are concerned about cervical spondylosis. At this point, it is important to analyze with the patient the many causes that can cause dizziness, including neurology, such as inadequate blood supply to the brain or minor cerebral infarction. There are also otolaryngology, with otoliths or abnormal vestibular function. There are also glaucoma, hypertension, and then cervical spondylosis. Cervical spondylosis occurs in many cases because of cervical instability, such as when the head is lowered or tilted, if there is a misalignment of the cervical spine, there may be dizziness. Many people like to stretch, and when stretching, if the cervical spine moves in a certain way and dizziness occurs, it may be related to the cervical spine. However, it is rare for dizziness to occur in the cervical spine, and it is also rare for dizziness to occur when the eyes are black. Therefore, many patients with dizziness may need to see orthopedics, neurology, and otorhinolaryngology in the outpatient clinic, and after seeing a series of departments, they may find that the cause is complex, and only one disease may play a major role, while other diseases may also play a minor role, so it is necessary to combine many clinical physical examinations and ancillary tests to determine the cause of dizziness.
