Headaches can be caused by cervical spondylosis?

Headache may be caused by cervical spondylosis, cervical spondylosis can be divided into nerve root type, vertebral artery type, sympathetic type, spinal cord type and other types. Vertebral artery type refers to degenerative tissue compression of the vertebral artery, showing insufficient blood supply to the posterior cerebral artery, inferior cerebellar artery and inner ear artery, resulting in various clinical manifestations. Sympathetic cervical spondylosis is a type of cervical spondylosis in which degenerative tissues stimulate sympathetic nerves and show neurological disorders. Most patients show symptoms of nerve excitation, and a few patients show symptoms of sympathetic inhibition. Brain manifestations include headache or migraine, sometimes accompanied by nausea and vomiting.
