Since standard acid-reducing medications haven't provided relief, your symptoms may stem from functional dyspepsia, nerve sensitivity, or an H. pylori bacterial infection. I recommend discussing an upper endoscopy with your doctor to directly examine your stomach lining, along with an H. pylori breath or stool test. For alternative treatments, your doctor might suggest trying H2-receptor antagonists (like famotidine), prokinetic agents to improve stomach emptying, or low-dose neuromodulators (like amitriptyline) to calm sensitive stomach nerves. These steps are very common and highly effective for finding the right relief.
