Hello, my name is Allison and I am 13 years old, I do not have any known simptoms of any sickness that would have to do with my heart, I have never had surgery. But I am feeling a pain in my chest in my heart area when I take a deep breathe or stretch a certain way, it hurts more on the bone than in my actual body but I am wondering what do you think might be the problem, I ha e only been experiencing this for about the past 15 minutes
