Hi,
Thanks for writing your query.
After reading your post, it seems that you are having symptoms due to infection of the gastrointestinal tract and needs medication.
You can take an antacid like
Omeprazole 40 mg along with an antibiotic like
Ciprofloxacin 500 mg twice daily and an antiamoebic like
Metronidazole 400 mg thrice daily. Adding a
probiotic will have added benefits.
You should take light meals prepared under hygienic conditions. Avoid spicy and oily foods.
Also maintain your hydration.
I hope this is helpful to you.
Thanks.
