How is the middle finger fingertip numb?

Fingertip numbness 1: Which fingertip is the main cause? If it is numbness in the radial side of forearm and thumb (including fingertip, which may appear at the initial stage), it is caused by the involvement of the nerve root of the sixth cervical vertebra. The numbness of the index finger and middle finger is the nerve root involvement of the seventh cervical vertebra. The numbness of the little finger and ring finger is the involvement of the nerve root of the eighth cervical vertebra. The above is mainly caused by cervical spondylosis, which can be cured by taking drugs for promoting blood circulation and removing blood stasis, acupuncture, massage and traction.

2. Fingertip numbness is suspected to be malnutrition caused by poor local blood circulation, such as wrist inflammation caused by long-term (long-term) typing.

Others: such as wearing gloves for a long time, the ring is too small (metal allergy), and the hands are exposed to toxic and harmful substances.

There are many reasons for general finger numbness. I suggest you pay attention to it.

Whether there is cervical spondylosis. Finger numbness in patients with cervical spondylosis has certain characteristics, either radial or ulnar, or five fingers. Sometimes not only the fingertips are insensitive, but also the forearm and upper arm are involved, accompanied by a decrease in grip strength. So what is the numbness of the fingers of patients with this disease?

A series of pathological changes in patients with cervical spondylosis, such as protrusion or prolapse of spinal cord, hyperosteogeny of posterolateral facet joints of vertebral body, joint loosening and displacement, can stimulate, pull and compress spinal nerve roots, resulting in reactive edema, root canal stenosis, adhesion of spinal nerve roots to surrounding tissues and finger numbness. Because of the different parts involved, the parts that produce numbness are also different. For example, when the nerve roots of cervical vertebra 6 are involved, the radial side of forearm and thumb are often numb; If the nerve root of the seventh cervical vertebra is involved, the little finger and ring finger can feel numb. From an anatomical point of view, sensory disturbance. In patients with cervical spondylotic radiculopathy, the two often coexist, that is, finger numbness and decreased grip strength. It is only because of the high sensitivity of sensory nerve fibers that the fingers are numb early and the symptoms are particularly obvious.
