Hi BUS! I just wrote to you on the other forum, I guess you really are scared. You said you are a LITTLE heavy,...does that mean only 5 or 10 pounds? You said that you had the pain ONE day... it may just be something you ate and someone who likes to play jokes or maybe someone who likes to act like they know it all took the opportunity to scare you. The pain for a heart attack usually is felt in the ARM. That pain might be that you gulped your food down without chewing it too much, or it could be heartburn or something else. Heartburn doesn't really have anything to do with the heart, heartburn is only called that because the pain feels the same, heartburn is ACID REFLUX (indigestion). If you had that pain only ONE day, that's probably what it is, but if you get it often, it's definitely something a doctor should know about, so, stop worrying before you scare yourself to death. Let your parents know about the pain.
