Not sure if its GERD or?

Sometimes, not every day. After I've eaten, i'll get a burning like heartburn, but it wont come all the way up my throat like heartburn normally does. it'll stay in my stomach, and do nothing else. it'll be there for a while and it goes away, or I get so busy I don't even realize its gone away. Does anyone else have this? is it GERD, or something else?? i'd google it, but from experience, that's a terrible thing to do.



Thanks.
