Hi I. So pleased that you are experiencing some relief
I have my stim just under two years for Failed Back Syndrome. I have noticed in the past few months that my stim feels stronger than usual. I put this down to the fact that the leads have scarred in by now. At first every movement meant the sensations went all over the place but now they are more confined which is definitely helping me cope with my pain much better. Plus some meds I still need to take.
