When i try pooping and push, my rib cages hurt at the bottom. what's wrong? also it hurts when i press in my stomach

You could have: scar tissue from prior surgery. Or a blood clot in the bottom of your lungs. Or intercostal muscle sprain from prior activity/strain. Or a hernia located near the rib. Or a hematoma inside the abdominal cavity. There are lots of reasons why you could have pain there. Please see a healthcare provider for proper diagnosis and treatment.
