relief seems to be more connected to bowel excretion, so it seems more likely that the pain is in the intestine.

and, this is a "familiar" pain - if this was a bladder attack, you'd think it would be a weird sensation i don't realize. it's not. it's just a stomach ache....

it feels like food poisoning, and maybe it is, still. but, whatever is causing it needs to be identified and removed.
