Numbness in the head and hands is mainly seen in the following cases: First, if the numbness in the head and numbness in the hands is accompanied by weakness in the hands, the patient should be asked whether there is dizziness, headache, and limitation of neck movement, and can go for a cervical MRI to understand whether there is cervical spondylosis caused by herniated cervical discs compressing the nerves. Second, if the numbness and weakness of the head and hands on the lateral side are acute and there is a history of hypertension and diabetes, go to the hospital for a cranial magnetic resonance examination to find out if there is a cerebral infarction or cerebral hemorrhage. Third, numbness in the head and hands, if the symptoms are unstable, ask the patient if there is any discomfort elsewhere in the body, such as wandering pain, somatic discomfort, and do the Anxiety and Depression Inventory to rule out somatization disorder.
