Thanks for writing your query.
After reading your post, it seems that you are having infection of your gastrointestinal tract and needs medication.
You should take an antacid like Omeprazole 40 mg once a day along with Domperidone
10 mg, an antibiotic like Ciprofloxacin
500 mg twice daily and an antiamoebic like Metronidazole
400 mg thrice daily. A probiotic preparation will also be beneficial. Dicycloverine
can help in relieving abdominal pains.
You should have light meals with less spice and oil and prepared under hygienic conditions. Also keep yourself well hydrated.
I hope this is helpful to you.
