Not sure why I am bothering to do this, since the thread is 6 years old. But just wanted to say --- I know exactly what you are experiencing, Fumes. I've had almost everything you describe over my 30 years of multiple fusions and PM. Hopefully you long ago recovered from your horrible surgery and PM experience. (I wouldn't be surprised if you're living off a huge malpractice suit) But undoubtedly you are still living with LBP. If there's anything I can add, 6 years later, that might help you, let me know.
