Does headache have a relation with cervical vertebra

Headache may or may not be related to cervical vertebrae. Cervical spondylosis can cause headache, such as sympathetic cervical spondylosis and vertebral artery cervical spondylosis. However, there are many causes of headache, and headache caused by sympathetic cervical spondylosis and vertebral artery cervical spondylosis accounts for only a small part of headache diseases. There are quite a few diseases causing headache, and there is little relationship between normal and cervical spondylosis. For example, subarachnoid hemorrhage, meningitis, encephalitis, intracranial tumors or mental factors can cause headaches, not necessarily due to cervical lesions.
