Sorry for how bad things are for you now
I don't know much about your current pain (or level) but I do know that any one of your problems (dx'd on the MRI) could be causing significant pain.
The facet problems alone can cause misery add that to your DDD, Spondy & Bulges....and you've got a perfect recipe for P A I N!
Are you currently on anything for the pain now? and are you being treated by a Dr for these conditions? I guess you are....if your considering a SCS.....Just know that from what I've read, SCS primarily help extremity pain & results aren't that great for LBP.
I'm glad you've found the board - there are others here who HAVE the SCS and can offer you more info on it.
