Hi i'm a 27yr female i had dinner 1hr 30mins ago i didn't eat much but now i feel like my food is in the very top of my stomach and it really hurts?

Acid reflux?: It's possible you could be experiencing acid reflux, where either the increased acid from your stomach trying to digest the food is congregating at the top of your stomach and causing your discomfort OR you actually do also have some undigested food also in the mix at the top of your stomach with the acid making you feel uncomfortable. You might try some TUMS (calcium carbonate) or even omeprazole (OTC) or cimetidine
