question: Three weeks ago I had upper stomach pain and nausea . Went to the clinic and they said I had a stomach. For the last three weeks, I have still had irritating stomach pain more after eating, nausea and green diarrhea . Also bad upper stomach rumbling and gas. I have bad acid reflux and had my gallbladder Removed 8 years ago after the birth of my son. It almost feels like the attacks I had when I had my gallbladder.
