Hi. Thanks for your query, albeit short and specific. Noted the history and understood the concerns. Well, Norflox can be taken for intestinal infection that is giving you the symptoms of upset stomach. But more important is the problem of proper diagnosis which would have been done by a clinical evaluation, examination by your Doctor and investigations of the stool, urine and blood as required to get the proper ALso needed are probiotics and activated charcoal tablets. Antispasmodic may required if the pain in abdomen is more. Plenty of oral fluid is very important to avoid dehydration. Oral rehydration liquid to combat dehydration. You can certainly take a normal food or diet if there is no nausea or vomiting.
