41-menopausal. lower left belly pain for 6 months, gas, diarrhea, fatigue., doc did ct scan 6 months ago w/o findings. could i still have a problem?

See GI doc: Have you tried keeping a food journal to see if certain foods bother you, such as lactose/dairy? Your doctor can test for celiac disease (gluten allergy) . An upper endoscopy may be needed to evaluate for gastritis (stomach inflammation). I also do stool studies to evaluate if you have inflammation in your bowels which may need a colonoscopy. I hope you get well soon!
