Thanks for writing your query.
It seems that you are having gastroenteritis
, an infection of the gastrointestinal tract.
It cannot be diagnosed by X-ray, so your X-ray was normal.
You need proper medical management which includes antacid like Omeprazole
20 mg once a day along with antibiotics like Ciprofloxacin
500 mg twice a day, antiamoebic like metronidiazole 400 mg thrice a day and probiotic
Take light meals with less spice and oil.
Take adequate oral intake of water and healthy fluids to maintain hydration.
I hope this is helpful to you.
