Hi Doctor, I started with diarrhea fifteen days ago and I went to the emergency hospital, and the doctor on call, after asking me some questions, he decided to prescribed me Metronidazole and Ciprofloxacina . I took them for 7 days and the diarrhea disappeared apparently. But three days later it returned again. So, I would like to know what happen with my digestive system since I m desperated because besides diarrhea I feel dizzy as well. Thank you very muck in advance.
