'You will never know unless you try"

I kept that in my wallet for ages and ages until it self-destructed.
I've been very lucky in escaping spinal issues - I should have them. I don't.
I merely have soft tissue and tendon damages which heat/cold therapies and exercises can help [IF I do them].
In starting to learn about PN and all it entails tho...I was surprised at how many also had spinal problems, many of them BAD.
In your case tho, [again from all my reading of other's experiences] I would bet that the steroids are your culprit...I've a friend who has cancer-and has gone thru more chemo and rads than ANY ten other people with cancer...She too is suffering from those pesky fractures everywhere. All this only recently more so, same as you.
I believe that medications to help us NOW can hurt us later. As in both your cases. I suscribe to the following newsletter that keeps me as up to date a a mere 'patient' can be: http://www.medicalnewstoday.com/ I get it weekly. And spend at least an hour going thru all the goodies.
Like Daniella, I'm not really a big meds person. They scare me at times, all the side effects and especially the lesser known or rare ones-as I seem to get those. BUT- Painkillers DO have a time and place in the course of things. AND your pain does sound like a time and a place when they should be tried. As well as the stimulators. You won't know, until you try!
My heart is with you on this one. Only You know what might be best for you. If there is a 50/50 success/failure rate in anything...just HOPE HARD that you are in the success category! I believe many here will be doing the same for you as well. - j
