Finger numbness may be caused by physiological factors such as cold, but also need to consider pathological factors such as cervical spondylosis, peripheral nerve compression syndrome.
1. Physiological factors: If the finger is cold, the blood circulation of the finger is poor, which causes a little numbness of the finger, and usually can be improved after keeping warm.
2. Pathologic factors:
(1) Cervical spondylosis: the numbness of the fingers may be caused by cervical herniation or cervical osteophytes, resulting in compression of the cervical nerve root or cervical spinal cord, which leads to numbness of the fingers.
(2) Peripheral nerve compression syndrome: due to prolonged use of hands, long-term chronic strain caused by the median nerve or ulnar nerve located in the finger by the bone fiber channel compression, resulting in a little numbness of the fingers.
Caused by a little numbness of the fingers for a variety of reasons, in order to exclude physiological factors, should promptly consult a doctor, after perfecting the relevant examination to determine the cause of the disease, under the guidance of the doctor to carry out targeted treatment.
