Re: Gastritis - upper left abdominal pain/ fullness
Gastritis means irritation of the stomach lining. Acid reflux disease is caused by stomach acid in the esophagus, where it doesn't below. They are separate conditions, although some of the treatments are similar.
Protonix usually helps. It can take a few days to see the full benefit. Be warned, that sort of drug sometimes causes dependency, and when you try to quit, some people get symptoms worse than they had before taking it. Some people don't have this problem. Either way, the Protonix may let the stomach heal. Also, it's probably the first thing the GI doctor will want to try.
