Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have got
stomach infection or food
poisoning after eating raw oysters as they might be contaminated with bacteria, viruses, parasites, chemical toxins etc..
It comes under seafood poisoning..
The symptoms of Vomitus along with fishy odour and
diarrhea are due to it ..
As the symptoms does not seem to be very severe you can start taking fluid replacement therapy like drinking lots of Oral Rehydration solution by dissolving oral rehydration salts in water..
You can also take Loperaminde for diarrhea only if there are a large number of stools more than 3 to 4 a day.
You can take Ondensarton for
vomiting..
Take a
soft diet and add Yoghurt in diet..
In case if symptoms worsen you need to consult an emergency room immediately and get evaluated..
Hope this information helps..
Thanks and regards.
