Thanks for writing your query.
After reading your post, it seems that you are suffering from infection of gastrointestinal tract and needs medical attention.
You should get yourself clinically examined and investigated.
Have light meals. Avoid spicy and oily foods.
You can take antibiotic like ciprofloxacin
500 mg twice a day along with metronidazole
400 mg thrice a day along with a probiotic
and an antacid like Omeprazole
40 mg once a day.
Also get your stool examined for Routine/Microscopic and for Occult blood.
I hope this is helpful to you.
