Loss of feeling in the hand may be related to cervical spine disease or shoulder joint disease, resulting in local nerve damage and prolonged pressure. If you stay in a low temperature environment for a long time, and your hands are too inactive, the local blood circulation is not good, which may also lead to loss of sensation in the hands. If one side of the hand is unconscious or accompanied by leg weakness and limited movement, it may be related to cerebrovascular disease, cerebral thrombosis or cerebral infarction. If there are symptoms such as severe headache and vomiting, it may also be related to cerebral hemorrhage, subretinal hemorrhage or brain tumor. Patients with diabetes or neuritis, patients with radial or median nerve injury, severe nerve damage or muscle atrophy may also have no feeling in their hands, so they should go to the hospital to determine the cause of the disease and take active treatment.
