Abdominal pain

Sorry if I posted this in the wrong group but I’ve been randomly getting this bad abdominal pain that lasts for hours and Idk why. Last night was the 4th time it has happened and it was awful. It feels like my stomach & intestines are burning and it’s somewhat similar to bad gas pains but prob 50x worse. I’ve experienced bad gas cramps constantly throughout my life, especially when I was younger but it’s never been this bad. Last night I tried rolaids, ibuprofen and pepto bismol but nothing worked. I also tried moving around and doing yoga poses for an hour and though it did get some gas out, it didn’t make the pain go away. It lasted for about 4 hrs non-stop until I finally fell asleep. I’m afraid to go to the dr bc it might be nothing but it’s awful and I dread the next time it happens. Does anyone know why I’m having this pain? Like could it be something I’ve been eating that I unknowingly have an intolerance for?
