NBR & TMI

For the last few months each time I eat I get this extreme pain in my abdomen & I have to go to the bathroom urgently & each time it's diarrhea. All the while I'm using the bathroom I am in pain & to the point where I'm nauseous as well. I don't have insurance & having a hard time finding a dr to see me without costing an arm and a leg... question is does anyone know if this could be IBS? Or is could this be something else? Not asking for a diagnosis just opinions... 😢
