Hi thanks for asking question.
I can understand your concern.
According to history you definetly having acute
gastroenteritis by food poisoning.
Take following measures......
Do you have taken any antibiotic???
If no then take
ofloxacin and
ornidazole combination drug for 5 days.
Maintain hydration with more water.
Take small meal with frequent interval.
Semisolid diet preferable.
Green leafy salad taken more.
Avoid excess fatty food for few days.
Probiotics tablet also taken.
I hope my suggestion will helpful to you.
Don't worry with above measures you will recover within few days.
If still no improvement we will do stool examination for search for
parasitic infection.
Take care.
