Hello and welcome,
Thanks for your query.
It looks like you have a stomach infection
, which is caused by consuming contaminated food or water. Although there are many possible organisms that can cause this, the most disease caused is Gastroenteritis
You will need to visit a doctor and start yourself on a course of antibiotics, he will also have to further discuss your presentation and he might also need to test your stool if required to confirm the diagnosis.
Try to refrain from milk, although curds/yogurt would help, as it is a natural pro-biotic.
I hope I have succeeded in answering your questions, you could write back to us anytime for further clarifications.
