Rantidine drastically reduced pain from gastritis. however, mild pain remains so prescription extended for 60 days. dr today conf no internal lumps vis physical exam. can i be sure of gastritis dx ?

Gastritis: I am unsure if an endoscopy was performed and if they checked for H pylori a bacteria that may exacerbate gastritis. Usually e don't do endoscopy unless the pain does not go away x 3 months.H pylori is easy to check for Avoid alcohol caffiene soda energy drinks smoking

Monitor and evaluate: Definitive diagnosis of your stomach condition can only be made with endoscopy, but the fact that Ranitidine helped is very reassuring. I think it is reasonable to extend the treatment that works. I would also recommend eliminating stomach irritants, like cigarettes, alcohol, spicy foods, sodas. If you continue to have symptoms despite lifestyle changes and treatment, you may need further eval.
