4 days ago, I woke up @ 4:00AM, because my stomach started feeling like it was being twisted on the inside. I had diarrhea & the pain in my stomach was like a 7 out of 10, it was like that for 10 minutes or so. After I let some gas go it started to feel better & the rest of my day was fine. But the next night my stomach started to twist alot & i went to eat & took some pepto bismol & after a while it got better. Now, today while i was laying on my bed, it started hurting alot. I had a good lunch & drank lots of water. Is there something wrong with me?
