Fingers feel numb, may be related to physiological factors, may also be cervical spondylosis, diabetic peripheral neuropathy, carpal tunnel syndrome and other causes.
1. Physiological factors: for example, stay in a cold environment for a long time, do not pay attention to the hand warmth, resulting in prolonged cold stimulation of the fingers, or sleep arm pressure for a long time, may cause poor blood circulation in the fingers, thus causing the fingers to feel numb.
2. Cervical spondylosis: If you suffer from cervical spondylosis, especially the existence of cervical disc herniation, the prominent cervical disc compression of the local nerve roots, resulting in pressure on the part of the nerve innervated sensory deficits, which may cause numbness of the fingers, may also be accompanied by neck and shoulder pain, dizziness and other symptoms.
3. Diabetic peripheral neuropathy: the disease can lead to patients with peripheral nerve damage, resulting in peripheral nerve innervation area of sensory impairment, which may cause numbness in the fingers, may also be accompanied by movement disorders and other manifestations.
4. Carpal tunnel syndrome: the disease belongs to a kind of nerve compression disease, can lead to the patient’s median nerve compression, causing local finger sensory impairment, may cause numbness of the fingers, may also be accompanied by finger weakness, sensory weakness and other manifestations.
Fingers feel numb, exclude physiological factors, should seek medical attention as soon as possible, clear cause after symptomatic treatment.
