Hello Looking at your description it seems to be food poisoning, acute gastroenteritis or food allergy If I were your treating doctor I would have advised you for a battery of tests like CBC liver function test and stool test for ova, cyst or protozoa. You may require a course of antibiotics under supervision of your doctor Meanwhile have lots of fluids including ORS and fruits juices to counter dehydration and electrolytic imbalances You can take anti acidity medicines like pantoprazole and anti.emetic like ondansatron for symptomatic relief Hope this answers your question Please feel free to ask for more clarification Best wishes
