Hi.
Thanks for your query.
Noted the history of eating at a restaurant yesterday night and not feeling well, stomach is cramping and burping badly, woke up around 1 am felt the need to go to bathroom, passed liquid stool as if passing urine through anus,
vomiting, vomiting at 3 am, still felling terrible.
All the history you have provided is indicative of developing
Gastroenteritis in response to the foods and/or beverages you took outside in a restaurant yesterday.
I would advise you the following in such a situation:
Go to ER, get vitals and other examination, clinical evaluation done and ask for investigations of blood and stool.
Get started on proper antibiotic,
metronidazole,
probiotic and supportive treatment such as fluids and electrolyte solution either orally and if not tolerated by intravenous route.
Complete the course for 5 days.
Consume only only boiled for 20 minutes and cooled water and home-made fresh foods.
