Has anyone ever felt what I can only describe as a live wire jerking feeling? It is in the left side closer to middle under my breast. I can go days without feeling it and then be shopping and it hits which stops me in my tracks. The duration of the feeling varies as does the jerking motion. It can happen once and be done or a few times in succession but it hurts and is very uncomfortable. Since I never experienced this before the PM I assume it is related. I did ask the doctor about it but he just strugged his shoulders.
