We're always happy to hear about benign results! That is the kind of news we love to hear! I didn't have this problem with my breast, but from my reconstruction scar. It was a small spot in the incision that just didn't seem to heal the way the rest of the wound did. It was just a little red and angry-looking, and it was itchy. They told me that sometimes this happens with internal stitches. The doctor dug around on it, couldn't find anything, and it eventually did heal over, but it took awhile. I would definitely let the surgeon's office know what's going on, just to be on the safe side. And again, thanks for sharing some good news with us!
