Hi Glassman
I too have spinal fusions in both L4/L5 and L5/S1 and it failed unfortunately.
I eventually went to the Pain Management clinic and tried all the conservative methods of pain relief, ie drugs, injections, infusions and then finally I was asked to try out the SCS......and I have to say that it is definitely worth a trial.
I have constant pain in my lower back and down my legs. The burning stabbing piercing pain in my legs is awful. The SCS is definitely great for this burning etc.......
You should definitely think about it and definitely go for a trial (make sure your approved as Rae mentioned) and if you get the results that you need then hey presto your on your way.....
I wish you the very best of luck
