I would also call your doc (if you are still around).

When that developed with my scs...it didn't get better, but got worse with time, and didn't resolve until the battery was removed.

Apparently this can be one of those potential negative side effects with the SCS. I still have pain/burning at the incision between the shoulder blades, and it has been seven years since it was removed.

Get it looked at. My mistake was to believe it was something I had done wrong, or that I was just paying too much attention to the problem.
