Thanks for reply to my post. I have been out of town and apolgise for not replying earlier. I have failed back surgery syndrome, (laminectomy and disectomy) nerve damage, and stenosis. I am scheduled to have the stimulator removed on 4/16 because it hasn't really helped me. I have had around 4 revisions to reattach the leads, and turning on the stimulator causes pain in my upper back that the dr. says is caused by the scar tissue?
