There is much info in the stickies above at the top of the page.....
Fiona has left a very informative site you might find very helpful.

Not sure where you are getting your info that SCS isn't approved by FDA for lower back as, that is what a great majority have had done with great success and that is usally one of the most common types performed.

May i suggest doing a bit more reading up on the websites people have worked diligently in putting in the information section of the SCS, so as not to have to repeat pertinent info that is already there.
OR ASK your doctor for more detailed information regarding your particular case especially it being very mult-dimensional medical case history.

Also, you may consider looking on the direct websites of the SCS manufacturers themselves.....

But again, the website in the stickies that Fiona provided pretty much spells it out in plain english. It also goes in to detail about the other very common SCS procedure done in the mid/upper back (cervical spin)

There is A LOT OF RESEARCH that needs to be done on this procedure.
MUCH MUCH MUCH research.
