The headache and neck pain may be caused by the radiation of the disease in the neck, or there may be lesions in both the head and the neck, to identify the cause and treat the symptoms. Headache and neck pain is a common phenomenon in daily life and a common clinical symptom. The most common cause is caused by neck lesions, such as cervical spondylosis, which can affect the nerves in the neck, causing neck pain and discomfort, and radiating to the head, thus causing painful symptoms. Cervical spondylosis can compress the carotid artery and cause a lack of blood supply to the brain, which can sometimes cause painful symptoms in the neck and head. Headache and neck pain can be caused by a lesion in the neck combined with pain caused by a change in the head, such as dermatomal neuritis in the head, migraine, intracranial occupying lesions, vascular lesions, and intracranial inflammation can all cause headache. If the headache is combined with neck pain, CT or MRI of the head should be done if necessary, and the neck should also be examined accordingly. The cause of the headache should be clearly identified and treated symptomatically. In summary, headache and neck pain may be caused by neck disease or neck and head pain may be caused by both neck and head disease. It is important to identify the cause and give symptomatic treatment according to the specific situation.
