Consider cervical spondylosis, cervical disc herniation, cervical posterior longitudinal ligament ossification, etc. Cervical spine nerve root compression is usually not self-healing. It needs to be treated with bed rest, bone traction, medication such as methylcobalamin and painkillers, and surgery. 1. Cervical spondylosis: Degenerative changes of cervical intervertebral discs can compress nerves and blood vessels, leading to shoulder and neck pain, skin numbness, allergies and other symptoms, which can be relieved by bed rest, bone traction, etc. The use of methylcobalamin and other neurotrophic drugs can repair damaged nerves and eliminate nerve edema. If the symptoms of cervical spondylosis are serious and conservative treatment is ineffective, surgery can be performed. 2. Cervical disc herniation: On the basis of degeneration of cervical discs, external force or other factors can lead to disc herniation, thus compressing the nerve root. Symptoms can be relieved by rest, bone traction, and the use of medicines such as methylcobalamin, etc. Surgery can be used to remove the cervical discs to solve the problem of compression on the nerve root when conservative treatment is ineffective. 3. Ossification of the posterior longitudinal ligament of the cervical spine: Calcification, sclerosis and ossification of the posterior longitudinal ligament of the cervical spine lead to narrowing of the vertebral canal, which in turn oppresses the spinal cord and nerve roots and causes sensory abnormalities in the limbs, movement disorders, headaches and other symptoms, which can be treated by rest, painkillers and surgery. All of the above medications should be used under the guidance of a doctor, and avoid self-medication. If cervical nerve root compression occurs, it is recommended to go to the hospital in time for early and regular treatment.
