Headache is a common clinical and spontaneous symptom that can occur alone or in the course of a variety of diseases. According to the classification of clinical symptoms according to the different pain structures of the head involved in the disease, it can be specifically divided into: traumatic headache (with a history of trauma to the neck and head), neurological headache (such as trigeminal neuralgia, postherpetic herpes zoster), primary vascular headache (such as migraine, cluster headache), secondary vascular headache (such as hypertensive headache, headache caused by intracranial tumor), myogenic headache (such as neck muscle injury and pulling headache, tension headache), meningeal headache (such as headache caused by meningitis), headache caused by altered cerebrospinal fluid dynamics (such as high cranial pressure headache), headache caused by systemic diseases (such as headache caused by influenza), etc. From the perspective of Chinese medicine, headache can be divided into external headache and internal headache according to the etiology and identification. External headache is mainly caused by wind, which can be divided into wind-cold headache, wind-heat headache and wind-damp headache, while internal headache is mostly related to the dysfunction of liver, spleen and kidney, which can be divided into liver-yang headache, blood-deficiency headache, phlegm-deficiency headache, kidney-deficiency headache and blood-stasis headache. Headaches can also be classified according to the location of the headache with reference to the route of meridians: sun meridian headache (posterior occipital pain), shaoyang meridian headache (migraine), yangming meridian headache (forehead pain), and sympathetic meridian headache (pinnacle pain). Treatment can be based on identifying the primary cause and relieving the primary factors; those with severe pain should be treated symptomatically to relieve the pain. In Chinese medicine, the treatment can be based on the etiology of the disease, and the treatment can also be based on the area of the headache with meridian inducing drugs or acupuncture. If severe headache is accompanied by fever and vomiting, or if treatment fails to improve, you must go to the hospital!
