I saw my pm and the stimulator reps yesterday. Just like you experienced, my pm believes my redness and swelling are related to the vancomycin powder that they put into my incisions during surgery. I think you are having better results that I have been having. Hard to find a good setting for the relief. I'm all over the place on the numbers. Yesterday's rep believed that the surgical rep mislabeled my leads and so I was really putting one lead way up to get the pain relief I was needing b/c it was a lead in a different spot. (If that makes sense.) I had to turn my stimulator off yesterday while driving home b/c I felt I was getting shocks from it with every bump I hit. Going back in 2 weeks so hope to get the programming looked at again.
