I am an oldie here, well sort of, and I have the Boston Scientific SCS for low lumbar and leg pain management. For me it works so very well I have been able to resume my profession leaving our family business to my family so we may increase the revenue stream. It has been truly a blessing to be able to practice again, and I reckon you would find if it is right for you the teaching profession may not be out of your grasp. Most anything you might want to ask is in the thread on this forum http://neurotalk.psychcentral.com/thread117854.htmls where the tale from injury through Trial Surgery of what was actually a Boston Scientific model then implant of said Boston Scientific SCS occurred. The best thing possible occurred for me when at the time for programming, I was allowed to program the unit to fit MY PAIN PROFILE and not what some rep would guesstimate.

If you have any questions I am here,
