Neurology is a secondary discipline about neurology, which is a relatively important discipline. Many diseases belong to neurology, including the more common clinical diseases such as cerebrovascular disease, headache, neuralgia, epilepsy, meningitis, dementia and facial neuritis. If there are frequent headache symptoms, one side of the headache may be a migraine, or it may be related to elevated blood pressure, encephalitis, brain tumors, etc. If there are symptoms such as severe headache, nausea and vomiting, it may be related to brain hemorrhage, subarachnoid hemorrhage, etc. If there are symptoms such as crooked mouth and slanted eyes, limited movement of one limb, numbness, etc., it may be related to cerebral infarction, cerebral thrombosis, etc. Symptoms such as inability to puff out cheeks, raise eyebrows and close eyes on one side of the face may be facial neuritis, so you should go to the neurology department of a hospital to have relevant examinations and choose a reasonable treatment method for the cause.
