The occurrence of arm numbness and hand numbness can generally be seen in a variety of situations, such as upper limb numbness due to compression of cervical plexus by cervical spondylosis. And then because of arteriosclerosis, such as arteriosclerosis of cerebral vessels and arteriosclerosis of upper limbs, there can also be insufficient blood supply areas, resulting in numbness of hands and arms. When arm numbness and hand numbness occur, corresponding examinations should be carried out, such as blood lipid test, blood glucose test, blood pressure measurement, and further carotid color ultrasound, transcranial Doppler examination, brain CT or neck CT, magnetic resonance examination. Through these examinations, the causes of hand and arm numbness can be identified. Finally, targeted treatment will be carried out.
