Should i go on a gluten free diet, to help with my stomach pain?

Depends: Gluten free diet is certainly indicated in patients with celiac disease aka gluten-sensitive enteropathy. It may also help in other conditions such as small intestinal bacterial overgrowth or some forms of ibs. However if you have not been diagnosed with the above conditions or have not been evaluated by a physician for your stomach pain you may be delaying treatment of a possibly serious problem.
