6-year-old girl said headache may be related to refractive error, upper respiratory tract infection, meningitis and so on. 1. Refractive error: if the girl is myopic, but do not want to wear glasses, resulting in long-term squinting, the eyes are always in a state of fatigue, which causes nerve fatigue-induced headaches. 2. Upper respiratory tract infection: in most cases, it is a stress reaction produced by the body, which is prone to increased nerve excitability, changes in blood viscosity, changes in muscle receptors, which induces and stimulates intracranial pain-sensitive tissues, thus prompting the patient to experience headaches and other symptoms. 3. Meningitis: Inflammation of the meninges due to viral or bacterial infections, etc. After the inflammation stimulates the meninges, the patient’s intracranial pressure will rise, and the brain and surrounding tissues will be compressed, resulting in pain symptoms. In addition to the above, headaches in 6-year-old girls can also be seen in other causes, parents are advised to bring their children to the hospital in time, with the help of doctors to identify the causes, and actively cooperate with doctors to deal with or treat.
