Hello, I am a female. My age is 20. I am having diarrhoea from 9 days before. It started 2 days before my period. Stool condition is very runny, like water. I feel very weak. I am having hypersomnia for my weakness. I go to toilet 3/4 times in a day. I tried some medicines. Those medicines was suggested by an Mbbs 4th year student. Medicines names are : Flagyl. That didn't worked. So he suggested me again : Amodis 500 mg. I used to take flagyl before. But, this time both medicines didn't worked.
