For these patients, the diagnostic and therapeutic reasons for the injection are both satisfied.

For an individual who has been out of work due to back or neck pain from a facet injury, the medial branch block may allow a return to work. With an auto accident injury doctor such as Arizona IMA, this happens very frequently.
