Hi,
Welcome to health care magic,
All these symptoms of fever,chills,shivering,abdominal cramps with diarrhoea are indicative of food
poisoning.
Food poisoning is nothing but acute
gastroenteritis due to toxins of contaminated food from infections like bacteria, virus,parasite etc.
Symptoms usually starts after 12 to 24 hours of eating,like nausea,vomiting,
abdominal pain,loose motions,fever,weakness,fatigue, headache,abdominal cramps due to water and
electrolyte imbalance.
As per your symptoms, you have this gastroenteritis and will require antibiotics, antispasmodics, antiemetics,probiotics and other supportive treatment as per your symptoms.There may be need of fluid and electrolyte balance in the body.
So,consult physician for proper treatment.
