Sorry to hear about your health
It seems like an acute gastroenteritis
Usually it is viral and start to get better in about 24-48 hours
As it is already more than 48 hours and you are not getting better so better see your GP as this will require an antibiotic course
You should keep yourself well hydrated.
Use Gatorade and diet containing banana,rice,bread and apple sauce for few days
You need to have a stool analysis and an antibiotic to get rid of the infection
Acute gastroenteritis can be linked to use of certain food if that food contain infectious organism
