In the most general terms, a spine specialist is a physician who focuses on the pathology of the vertebrae, intervertebral discs, joints and neural structures of the spinal column and the spinal cord.
A neurologist might be the doctor of choice if your back or neck pain is chronic and longstanding, as she or he is an expert in the origins of pain. A neurologist does not perform spine surgery; instead, she will examine how well your nerves function, prescribe medication and refer you to on to another specialist, as appropriate.
