It's been awhile! I have had the spinal cord stimulator in for over a year. The trick is to get the stimuli in the right area of the face-not easy. I have had the different programs changed once. I will say that it has helped. My pain has decreased in most areas, however, I am experiencing more eye pain than I was before. I don't know if this was due to the cataracts taken off my eyes or not. I am going to see a neurological opthamologist next week. In summary, I would say the stimulator has helped me.
