I had revision lumbar surgery L2 thru S1 on January 7th , 2014. The nerve pain has been resolved,however, I am experiencing severe post operative pain at S1 where the surgeon anchored screws into my pelvis. The surgeon wants me to stop using Hydromorphone, which I understand . I am not dependent on the medication, but it does resolve the pain. Therefore, what can I Take to help with the pain? What can I do physically to reduce pain other than physical therapy? What is the prognosis and success rate of this surgery? What, if any, are physical limitations ? Thank you.
