The main manifestations are neck and shoulder pain, dizziness and headache, numbness of upper limbs, muscle atrophy, spasm of both lower limbs in severe cases, difficulty in walking, and even paralysis of all four limbs, urinary and fecal disorders, and paralysis. Disease classification, nerve root type: degenerative changes in the cervical disc or stimulation of osteophytes, compression of the spinal nerve root, causing sensory and motor dysfunction of the upper limbs, often manifesting as motor impairment or sensory numbness of one upper limb segment.
