Fusing vertebrae in the cervical spine (the top 7 vertebrae of your spine) may help ease neck and arm pain. It may also help relieve progressive paralysis caused by compression of your nerve roots or spinal cord.
Meningitis is an infection in the fluid that covers your brain and spinal cord. It may cause headache, stiff neck, irritability, fever, drowsiness, nausea, and vomiting.
Cervical radiculopathy is caused when the nerve that goes from the spinal cord to the arm is irritated or has pressure on it. This may be caused by a bulging spinal disk or a narrowing of the spinal joint because of arthritis.
