Hi Terry ~ I'm sorry you're sufferiing so. I know all too well what it's like, since I'm a 26 yr chronic pain patient, and have had 2 open spinal surgeries.
Terry, I would INSIST that my doc run another MRI on me. It's been 2 years since your surgery, and you are due for another one anyway. Since you had surgery, it's been my experience that the level either above or below the surgery site will FAIL. That could be your problem. Or it could be scar tissue for that matter. Even if your MRI is fine, you still should have another one just to make sure.
Sometimes after we've been in pain for so long, our neuroreceptors don't know enough to shut off, so they keep sending pain signals even if there isn't any pain. I'm not saying you don't have any pain, but it's a thought to consider. Our whole central nervous system can get screwed up.
I wish you the very best of luck. Please let us know what your MRI says. God bless. Hugs, Lee
