Thanks for writing your query.
After reading your post, it seems that you are suffering from acute infection of the intestines and need proper management.
You should send a sample of your stool for culture/senstivity and start antibiotic according to the reports for complete recovery from the infection. Till the reports come you can start ciprofloxacin
500 mg twice a day along with metronidiazole 400 mg thrice a day and antacid
20 mg once a day. Proiotic preparation shold also be added.
Antispasmodic like drotaverine
can be added for pain in abdomen.
Also take light meals with less spice and oil. Drink pure water only.
I hope this is helpful to you.
