Why does my stomach hurt when i breathe?
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
You may have pulled or damaged a stomach muscle. Since they move when you breath and injury would hurt.
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....
