Hi @hellokitty5 and welcome to Mayo Clinic Connect. I echo what @ken82 suggested regarding a second opinion from a GI physician. Here on Connect, we have a broad membership of people with all sorts of medical conditions. This offers a wide range of experience and medical "tips" even though it is not professional medical advice.
When you had the CT did your doctor order it with contrast? Did she suggest any other testing like a gastric emptying test or endoscopy/colonoscopy?
