Tension headache includes headache caused by both muscle tension and nerve tension, which mainly manifests as a feeling of pressure and heaviness in the neck, head and face. Patients report a feeling of tightness in the head. Mental tension causes continuous contraction of the frontal and temporal muscles of the head, or stimulation such as high blood pressure or cold directly causes impaired blood circulation in the muscles, producing local accumulation of carcinogenic substances, or damage to the tissues of the head and neck directly produces carcinogenic substances, resulting in headache. The onset of the disease is slower than migraine, but emotional excitement or extreme worry can also cause acute attacks of tension headache, and pain exists continuously day and night, which is characteristic of the disease. Most of them are accompanied by symptoms of neurosis, and there are no obvious positive signs other than muscle pressure. Tension headache is extremely closely related to migraine, and some patients initially present with symptomatic migraine and have the characteristics of myotonic headache after prolonged attacks. There is some overlap between the various manifestations of the two types of patients. The symptoms that are characteristic of the two types of headache have not been found yet, which means that the various symptoms only have the difference of the incidence of the two types of headache, and have relative value in the diagnosis, but not absolute significance. Relatively speaking, tension headache often has a feeling of pressure and tightness, and the headache mostly occurs in the occipital region and the top of the head, while migraine can be seen as a full headache and pain in any part of the head. Tension headache often occurs due to mood swings or irregular mood swings, and the pain is relieved when hot compresses or local massage are applied, and the headache improves after recuperation or sleep, while these characteristics of migraine are not obvious. Tension headaches tend to persist and do not disappear within an hour. There are no visual aura symptoms of migraine with aura, and unilateral limb hemiparesis or speech disorders are rarely seen. In order to distinguish tension headache from migraine, a detailed history and patient examination are necessary, and only by fully grasping the patient’s information can we make a correct judgment based on this.
