Hi, from the symptoms it suggests you seem to be having an issue with your upper gastointestinal system more confined to problems in your stomach and esophagogastric junction. symptoms suggest an gastritis
or an gerd(gastroesophageal reflux disease).both can be treated conservativelly with antacids. but if symptoms persists i suggest you to have an upper gastointestinal endoscopy
to confirm the diagnosis and will help in planning a definite treatment. life style modification,exercise,diet habits are all other aspects to be considered .
