What do you call a certified back specialist?

Varied: There are many specialist associated with the spine. As an orthopedic spinal surgeon I am bias to that specialty as the premier source for treatment. But there are equally good neurosurgeon in the field. When surgery is not needed, there are interventional anesthesiologist who are trained in treatment of disorders that respond to injections. P.T, chiropractors, & pcp should be consulted.
