Why does my stomach hurt when i breathe?
Sometimes pain can come from breathing in when you have a chest cold. Which may be the case since its the upper part or it may be indigestion, depends what you drank or how fast you ate.
You may have pulled or damaged a stomach muscle. Since they move when you breath and injury would hurt.
because of some sort of infection...your stomach acid burns the top of your stomach....that's if the top of your stomach hurts...and you feel like when food is stuck in your esophagus
Go to a doctor....there are many reasons and you will need to answer the doctor's questions so you can be diagnosed, and treated, if necessary....
