Ischemic hand numbness can be seen in numbness caused by local ischemia of the hand, which may be due to local blood circulation disorders in the hand or nerve damage due to occlusion or stenosis of blood vessels, and the patient can develop numbness in the hand. Ischemic hand numbness may also be caused by cerebrovascular ischemia, which can be seen in the hemi-oval center, radial crown, and thalamic microischemia, and the patient can develop hand numbness, which can be accompanied by numbness of one limb in severe cases. For the above condition, we should actively treat cerebral ischemia, and we can give the patient antiplatelet aggregation, improve circulation, and activate blood circulation and remove blood stasis. It can also be combined with acupuncture and massage to improve hand numbness, as well as B vitamins.
