Back pain: I understand there are a number of board certified pain management specialists available. They should be able to arrive at solution that will help.

You really should : First get a second opinion from an orthopaedic spine surgeon or neurosurgeon. Then, you should see a pain management specialist if the second opinions did not recommend any further surgical intervention.
