Unfortunately jo jo, stomach pain shouldn’t be associated with leaky gut. Leaky gut relates to allergies caused primarily by inflammation. The main symptoms associated with leaky gut are allergies to almost all foods and lack of nutritional absorption. I would consider getting your allergies tested with an allergist, or consulting a GI doctor. An allergist would be able to confirm that you have are allergic to many of the foods you eat. A GI doctor might know of other testing and ways to diagnose.
