I know someone that had spinal stenosis and spondylolisthesis pinching nerves and it took 2 tries for surgeon to "clean out" the right amount.. he was conservative the first time, but a year or so later the paint came back, the second surgery worked much better..
We also have a Spinal forum - you can post there also & if you have a MRI report you can share it there - sometimes the written report wording can help with getting better info.

Did your therapy try TENS, IF stim, low level/soft laser, ultrasound, traction, anything like those?
Maybe a SCS might be something to look into since some meds are an issue.
We have a SCS sub forum also..
most of the things I mentioned can be found with a site search - in past threads or posts..
