Is it possible for a 14 year old boy to have a heart attack? ok. I am 14 years old, 5.6 and 160 pounds. I get this feeling in my chest (little bit left of my sternum). Its not a pain, but i still feel it. It happens only occasionally. My grandma, uncle, and cousin all of bad hearts. My mom does not, however. Is it possible that these pains can be a heart defection? I am overweight, but its not all fat... and I am very stressed out (i know hard to believe for a 14 year old, but i am) and also, i get these pains when im nervous too if i get in good shape, do u think these pains will go away?
