I think I will be coming here every time a question or concern comes to mind, so sorry if you get sick of hearing from me! Just wondering: Has anyone here actually experienced PM leads coming loose? I am a little over a week out from surgery, and that has been stressed more than anything else...Don't raise your arm or they'll come loose...Don't carry heavy items or they'll come loose...I have forgetful moments when I do something I probably shouldn't, and then I panic. How common is that? How would I know? How serious is it? This afternoon I struggled to get a sealed lid off a container, strained a bit & felt a twinge in the left side of my back. Loose lead or pulled muscle? Silly, I know, but I could use some reassurance!
