After getting food poisoning from a mussel I now can't eat other shellfish. Will I get better with time?

After getting food poisoning from a mussel I now can't eat other shellfish. Will I get better with time?

I don't know: Is this a question about your psyche, or is this a question about whether or not you will get over this food poisoning episode? If it is the latter, then chances are yes, you will get better.

Either way, you will, or you won't. Only you will provide the answer. Me, i'd just avoid mussels...

Can wasabi peas go bad and cause food poisoning? Ate some for first time ever, already were sitting in cupboard for while. Felt flu-ish next few days

Can wasabi peas go bad and cause food poisoning? Ate some for first time ever, already were sitting in cupboard for while. Felt flu-ish next few days

Not food poisoning: Dried foods like wasabi peas are an unlikely cause of food poisoning, and "flu-ish" symptoms don't suggest it. The main symptoms of food poisoning are gastrointestinal -- nausea, vomiting, diarrhea, etc. And food poison symptoms generally clear up on their own within 1-2 days. Almost certainly your symptoms have nothing to do with the wasabi peas. See a doctor if they continue or become severe. ...Read more

This is the second time in two weeks I've thrown up after eating a salad. Could it really be I have food poisoning or do I have some sort of allergy?

This is the second time in two weeks I've thrown up after eating a salad. Could it really be I have food poisoning or do I have some sort of allergy?

The chances for anaphylaxis (a life-threatening form of allergic response) are higher when there are itching, flushing, and /or hives. If you can't figure out which ingredient in the salad caused your problem, consult an allergist. ...Read more

Food poisoning? I got severe stomach pain and diarreah out of nowhere, every time I eat I get sick farted bloody mucus as well
