I have a sister who is in her 40's and she has mentioned this chest type pain on and off on her left side. Not real strong at all. She says it could be heartburn, anxiety or even her neck and back out of whack (which she has chronic problems with that!) so my question is, how do you know if its something serious going on with the heart? If it's a heart condition, is there something more to look for?
Thanks!
Thanks!
