I woke up and noticed one side of my stomach felt larger than the other, on the right side just below my belly button. It also feels slightly harder when I poke it than the other side and hurts a little. Is this just a lump of food stuck in my intestine or should I be worried? (I also currently have strep and I'm taking penicillin for that).
It is possible that it is as simple as some stool in your colon that should move through in a day or so, but if it is persisting we should check you out.
