Stimwave lead came aprt in my back

I have a Stimwave A8 neurostimulator. The lead is implanted in my lumbar. I wear the battery and the antennae straps to the exterior of my back. Recently I had to have an injection of the L2 because of a disk bulge. The pain management doctor noted on the screen that all the parts of the implanted lead had fragmented to various parts of my back. I was stunned. Rather than a linear pattern of successive, square dots forming the lead, I was looking at little square dots scattered around my vertebrae. This is a catastrophic break of the implant. Has anyone heard of this happening before and is there any advice? Thanks
