Re: Sharp stabbing pain in left side of chest!
If it worsens with a deep breath it is costochondritis, an inflammation of some tendons or ligaments in the chest. It hurts a lot, often for quite a while (weeks) but goes away on its own.
Take some naproxin (ALLEVE); it helps a lot with the pain.
In the future try stretching your chest well, arms overhead, before your workouts to avoid doing it again.
It is almost CERTAINLY not your heart. Heart pain never worsens a lot with a deep breath or a change in body position.
