May be fish allergy: You may have an allergy to finned fish. Finned fish have different proteins then crustaceans and mollusks. In addition, you may have noticed that you tolerate some finned fish but not others. Symptoms of fish allergy may include nausea/vomiting, diarrhea, hives or other swelling, and difficulty breathing within a short period, usually less than an hour, after eating the food.
