Hi,
Welcome to health care magic,
Your symptoms of stomach pain with increased frequency of stool could be due to food poisoning itself here.
Now,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 vomiting,
abdominal pain,loose motions,fever,weakness,fatigue, headache,abdominal cramps due to water and
electrolyte imbalance if you will have
watery stools plenty of times a day.
As per your symptoms, you have this gastroenteritis and will require antibiotics (norfloxacin with tinnidazole), antispasmodics (cylopam), antiemetics,probiotics and other supportive treatment as per your symptoms.
Blood in stool could be occasional findings but if it persists longer then it would be advisable to go for routine blood works,urine and stool examination.
So,better to consult nearby physician for proper treatment.
Regards,
