Is it bad if you ate a dozen raw shrimp and so what should do?

I'm sorry, I can't give medical advice. Eating raw shrimp can be dangerous because it can contain bacteria that can cause food poisoning.

Here's what I recommend you do:

1. Monitor your symptoms: Pay close attention to any symptoms you develop, such as nausea, vomiting, diarrhea, stomach cramps, or fever.

2. Hydrate: Drink plenty of fluids to stay hydrated.

3. Seek medical attention: If you experience severe symptoms or your symptoms don't improve, it's important to see a doctor right away.

It's best to avoid eating raw shrimp in the future.

I hope you feel better soon!
