If a patient has headache accompanied by vomiting and physical signs and symptoms, such as limb sensory disturbances or motor disturbances, intracranial organic lesions should be excluded, and common diseases include cranio-cerebral tumors, cerebrovascular diseases and infectious diseases of the central nervous system. In patients with cranial tumors, the onset is usually subacute and the patient’s condition can gradually worsen. Infectious diseases of the central system mainly include encephalitis and meningitis. Encephalitis is caused by viral infection; meningitis is caused by bacterial infection. Patients may have fever at the same time and should have blood tests. Patients with encephalitis generally have a blood count that indicates high lymphocytes; meningitis generally has a blood count that indicates elevated white blood cells and elevated neutrophils, and if necessary, an electroencephalogram should be checked and cerebrospinal fluid should be drawn for pathogenic testing to clarify the diagnosis. In addition, it may also be caused by tension headache. Tension headache is a primary headache disease, mostly occurring in young and middle-aged patients, mainly manifesting as persistent swelling, aching and dull pain in the occipital neck, frontotemporal region bilaterally, and most patients have headache lasting for days, weeks, months, or can last for years, and is mainly treated symptomatically.
