Tension headache (TTH) is a headache caused by tension headache, which is characterized by a feeling of tightness and pressure in the head. Tension headache (TTH) is the most common type of headache, and its prevalence is generally considered to be higher than that of migraine, accounting for about half of all outpatient headache patients.TTH is a diagnosis formulated by the International Headache Society (IHS) in 1998 in the classification and diagnostic criteria for headache disorders, cerebral neuralgia and facial pain. TTH is a diagnosis developed by the International Headache Society (IHS) in 1998 in the “Classification and Diagnostic Criteria for Headache Diseases, Cerebral Neuralgia, and Facial Pain,” and the name is now widely used internationally. TTH includes the muscular constriction headache and psychogenic headache components of the headache classifications made by the AdHoc Committee in 1962. Tension-type headache is the most common type of headache among adults, and its onset is associated with psychosocial stress, anxiety, depression, psychogenic factors, muscle tension, and abuse of pain medications. The disease occurs mostly in adults, especially in women, and most of the disease duration is long, which can last for decades, often recurring, mild headache only occurs when there is obvious tension or depression, and the chronic headache can last for several days or weeks. It is usually characterized by bilateral persistent occipital or frontal dull pain, which may extend to the whole head, often with a feeling of pressure and heaviness or tightness around the head, although sometimes mild dizziness, blurred vision or tinnitus may be present, but rarely with nausea, vomiting or general malaise. Nervousness and anxiety can induce the disease. Headache caused by muscle contraction is the most common of all headaches, it is caused by the contraction of the head and neck muscles, usually, the site of the headache is not consistent with the muscles, it will be transmitted to the forehead, both sides of the temples, and even the orbital region of the eyes, due to the different parts of the pain, it is often puzzled by the cause, in fact, just a contraction of the muscles of the neck caused by the contraction of the head and neck muscles, this type of headache is often due to the pressure of the work or family pressure increases and becomes more severe, it is often due to work pressure or family pressure increases and becomes more severe. This type of headache is often due to work pressure or family pressure to increase and become more serious, it may also be due to walking or sleeping posture is not correct, or buried in the work too long and cause, regardless of the cause, this type of headache is temporary, and as long as you take the general headache medication can stop the pain. Headaches caused by eye fatigue are similar to those caused by muscle contractions, but the former are clearly related to eye use, and can be exacerbated by overuse of the eyes. There is also a relationship between emotions, such as frustration and anxiety, prolonged periods of stress and arthritis in the neck, which can also cause this type of headache. It is generally believed that tension headaches are associated with pericranial muscle disorders or psychogenic headaches. In the new classification, TTH is also subdivided into 2 subtypes according to the timing of the headache attacks and pericranial muscle disorders: 1. Episodic tension-type headache (ETTH) (1) Episodic tension-type headache associated with pericranial muscle disorders. (2) Episodic tension-type headache not related to pericranial muscle disorders. 2, chronic tension-type headache (chronictension-type, CTTH) (1) with pericranial muscle disorders related to health search chronic tension-type headache. (2) Chronic tension-type headache not related to pericranial muscle disorders.
