What treatment when sick after eating a bad oyster?

If you feel sick after eating a bad oyster, it's important to stay hydrated by drinking plenty of fluids, such as water or an electrolyte solution. Over-the-counter medications may help alleviate symptoms like nausea or diarrhea, but it's best to avoid anti-diarrheal medications if you have severe symptoms. If symptoms persist or worsen, seek medical attention promptly, as foodborne illnesses can sometimes lead to serious complications. Always consult a healthcare professional for personalized advice.
