Three months of chronic diarrhea and stomach pain is a red flag that requires formal medical evaluation, not self-medication. Since Oflox OZ (an antibiotic/antiprotozoal) did not help, your condition is likely not a simple bacterial infection. It could be due to Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD), celiac disease, or food intolerances. Please do not take any more random antibiotics, as they can worsen diarrhea by disrupting healthy gut bacteria. You must see a gastroenterologist for proper diagnostic tests, such as stool analysis, blood tests, or a colonoscopy, to find the root cause. Meanwhile, stay well-hydrated with oral rehydration solutions (ORS).
