Depends, has it happened before? Does the pain go anywhere else? When does it happen? -I've had a related problem for about three years and I haven't died yet. Though, my parents made the assumption of calling my heart troubles a bone problem, so make sure to explain it correctly to the doctor+family, which you should asap. If you've got squeezing pain, and don't get your heart checked out thoroughly, you might miss something and end up like me in serious pain everyday =\ I'm just now getting the right testing done...But its so bad now I can't work or do much of anything, but don't let it get you down, and remember to see your doctor - !
