I had a permanent SCS implanted in April 2011. It has been working awesome. At my post-op visit my Boston Scientific Rep set my program so well that I have never changed programs, and rarely increase the intensity. However, just within the last week the stimulation has moved. It is supposed to be in my lower back, and now I am getting the majority of the stimulation in my legs and a lot in my feet. Occasionally in certain positions I get it by my ribcage/abdomen. I talked to my BS rep and we are meeting to try and re-program, but he did sound concerned as this change has come on all of a sudden. He asked me if I had recently fallen, and I have not. So I guess does anyone know if it is common to have a lead move almost a year after surgery? And if it has moved and I cannot get my pain relief back after programming, how do they fix it? If it is surgery is it as awful as when they implanted the device? I had awful pain in my upper back for many weeks. Any help/advice would be appreciated.
