I assume your pain is mostly central lower back pain (LBP) and it does not favor one side more than the other. If it is more on one side, this would change treatment decisions.
If pain is centered, I would start out with large volume epidural steroid injections (maybe as many as two to three) and a heavy does of rehab pilates to strengthen your core muscles. If pain is more one-sided, then this is a different discussion.
