Okay so not recurring then Has it been getting worse? Or did it start two hours ago and more or less stay the same? I guess at this point sleeping on it is all you can do, but yeah, definitely go to the doctor ASAP if it sticks around. Depending on how well you think your mother will handle it (as freaking her out is probably not high on the list of your priorities right now lol), letting her know that you're not feeling well & may want to go to the doctor tomorrow might be a good idea too. Symptoms of a heart issue are unfortunately a little different for everybody so there's no surefire way to tell if there's a problem there. Any arm or shoulder pain, breathing trouble, etc? Or is this isolated?
IIRC, heart burn is more of a burning in the pit of your chest & throat, like the sort you feel when you need to throw up. It's from stomach acid. Not to scare you, but this doesn't sound the same; it sounds more serious and I'd recommend seeing a doctor about it. Most likely, especially at your age, it's probably something minor -- but obviously heart/lung issues are really important things to address if you think you might have one. EDIT: Is this recurring or?
(It's a ratings thing, most likely.)
