4 weeks ago I started getting heartburn which developed into chronic indigestion. After taking Antacids for a week I went to the doctor and described my symptoms. He asked me to do a stool sample as he wanted to check for Helicabactor Pylori Infection. After waiting 5 days the results came back as negitive. However the symptoms persist and have now got worse. I am taking a medication called Lansoprazole, which is a Proton Pump Inhibitor and this is still not helping. I also take Gaviscon after meals. The doctor now wants me to have a Barium Swallow X-Ray and Endoscopy, as the doc believes I may have a stomach ulcer. I am so nervous about these test but know it is important to have them done. My other symptoms include hard to swallow as it feels like I have a lump in my throat, belching, hiccups, burning sensation in my upper GI and I am now vomiting. Has anyone experienced symptoms like this who could possibly give me advice or reassurance, or has anyone had the tests I need to have???
