High pillow, especially in the back of the head position is easy to lead to cervical spine physiological curvature straightening, long-term high pillow even easy to lead to cervical spine physiological curvature anti-bow. This is because the normal human cervical spine is like a bow is flexed. When the long-term high pillow leads to neck suspension, the neck by gravity over time will lead to straightening of the curvature or even anti-bow. Eventually, the peripheral neurovascular pressure and protective muscle spasms lead to discomfort throughout the neck, especially in the posterior occipital region, often accompanied by dizziness and headache. This type of cervical spondylosis is often seen in young people, who work with their heads down for long periods of time. The vast majority of clinical x-rays of young people who come to the clinic with neck discomfort are of straightened physiological curvature, with no signs of cervical metamorphosis at all. In the old textbooks, the cervical pattern in cervical spondylosis basically refers to this. However, young people before the age of 30 are prone to this in clinical practice. The majority of them have a high pillow habit when asked about their medical history.
