Hello, for the last 2 months almost I have been suffering from what my doctor thinks could be stomach acid problems or an ulcer coming on. I have been on Dexilant for almost a month but still experience some kind of symptom daily --from stomach pain or burning, reflux or indigestion, or discomfort behind my sternum. Today I have been feeling sick, no pain nor twinges, just queasiness that I can t shake. Where is this feeling coming from all of a sudden? What can I take for relief? I am scheduled for an endoscopy next week. I am 58, woman. I have throughout my life experienced short lived stomach discomfort, indigestion but never lasting this long nor with these multiple symptoms. Thank you.
