One side of the neck and shoulders of the upper limbs repeated pain, numbness, head up, fingers numb, activity is not working. Such as small fingers numb often caused by C8 nerve root compression. Cervical spondylotic radiculopathy accounts for about 60% of all cervical spondylosis. It is the highest incidence rate in cervical spondylosis. It is more common in middle-aged and elderly people. However, it seems that many people in the youth also have morbidity, and men are twice as many as women. It is more common to be a manual worker.

As the number of episodes increases, the symptoms can gradually increase.

Cause

Nerve root type: compression of nerve roots; can cause hand activity is not easy.
