Numbness of the hand during the day may be caused by nerve entrapment, peripheral neuropathy, cerebral vascular lesions and other reasons.
1. Nerve entrapment: Nerve entrapment such as strain injury, incorrect posture, carpal tunnel syndrome, elbow syndrome and cervical spondylosis, etc., can easily lead to nerve entrapment, mainly due to the normal tissues or hyperplasia, compression of the conduction nerves of the hand, resulting in abnormal conduction of the nerve signals of the hand, and the symptom of numbness of the hand during the day.
2. Peripheral neuropathy: peripheral neuropathy, such as diabetes, vitamin B1 or vitamin B12 deficiency, alcohol consumption, etc., due to high osmotic pressure, lack of nutrition, alcohol stimulation, resulting in peripheral nerve damage, poor conduction function, which can lead to daytime hand numbness symptoms.
3. Cerebrovascular lesions: cerebrovascular lesions are generally the opposite side of the brain blood vessel infarction, sclerosis, stenosis, plaques, resulting in limb ischemia, resulting in nerve conduction problems in the brain, leading to daytime numbness phenomenon.
If you find a daytime hand numbness, it is recommended to consult a doctor in time, under the guidance of a professional physician to identify the cause of the disease, and standardized treatment.
