Numbness and weakness of the hands can be caused by cervical spondylosis compressing the cervical nerves, cerebrovascular disease, cerebral infarction or cerebral hemorrhage, or diabetic peripheral neuropathy. The diagnosis needs to be made based on the patient’s medical history, age, cerebrovascular risk factors, and comorbid symptoms. If cervical spine is considered to be the cause, it is recommended to take cervical spine four-position film or cervical magnetic resonance to make a clear diagnosis, which can be combined with the treatment of traction, acupuncture and massage. Normally, we should pay attention to the improvement of life posture, avoid prolonged low head work, avoid prolonged playing cards, do not pillow too high pillow. If the numbness is in both hands, it can be seen in diabetic peripheral neuropathy, which should be treated with blood sugar control and nerve nutrition. If the patient’s numbness is single limb, at the same time there is weakness or accompanied by speech impediment, considering the cerebrovascular disease, must consult the neurology department of the hospital in time.
