Frequent headaches may be caused by physiological factors, cervical spondylosis, migraine and other reasons. 1. Physiological factors: excessive academic stress, mental tension, anxiety, cold, lack of sleep and other factors can lead to cerebral vascular spasm, brain nerve stimulation, frequent headache symptoms. 2. Cervical spondylosis: vertebral artery-type cervical spondylosis is due to degeneration and proliferation of the cervical spine, which compresses the vertebral artery, leading to insufficient blood supply to the brain, ischemia and hypoxia of the brain tissues, resulting in frequent headaches. 3. Migraine: Migraine may be related to heredity, endocrine disorders and other factors, and the pain mechanism may be related to the release of endogenous pain-causing substances, such as calcitonin gene-related peptide, and the impairment of endogenous pain control system. Patients often have throbbing head pain, accompanied by nausea, vomiting, photophobia and other manifestations. Patients with frequent headaches should go to the hospital in time to improve the examination and give targeted treatment as soon as possible after the cause is clear.
