Hi there, My friend is 55 years old and is sitting here complaining that for a couple of days, she s had pain from her shoulder to her elbow. She has a pacemaker, and it was put in 2.5 years ago, so she feels it s unrelated, but I m worried it is. She said she feels like her heart flutters when there is pain. I m wondering if she should go see someone, (i.e. The hospital?) or if she is okay. Thank you.
