I have been experiencing abdominal pain and diarrhea for the past 2 days. My stool test shows infection with Giardia lamblia. My doctor prescribed Ornidazole 500 mg, 2 tablets per day for 5 days. I would like to know whether Metronidazole is more effective than Ornidazole, or if Ornidazole alone is sufficient for treating this infection.

Both are effective. Ornidazole has a longer half life and fewer doses. If prescribed, it is safe to continue as advised by your doctor.

I had vomiting and loose motion so my doctor said I have a stomach infection and advised me to get blood and urine reports. I am also having regular back pain and my mouth has a sour taste. I have attached my reports.

I have been suffering from gastric problems for the past four weeks and recently I have started noticing black stools. I am attaching my report here and would like to know what the issue might be.

I am experiencing what may be a navel displacement, as I have pain in my belly and my digestive system is not functioning correctly. I went to the doctor, who gave me medicines and did some tests, but everything came back normal. Still, I feel pain and indigestion. I also notice a pulse just an inch above my belly button. What should I do?
