Hi, we had full lobsters for supper and about half hour later my 10 year old daughter is complaining about stomach cramps in her lower abdomen. These were pre-cooked frozen lobsers so we steamed them to warm them up - that's it. She had the stomach flu 2 weeks ago and said this pain is worse. It has been about an hour and it still hurts her. She isn't having any trouble breathing, nothing is swollen, no tingling around the mouth. I can't recall if she has had lobster before, I know she has had crab legs (2 years ago atleast, maybe 3) and she loves shrimp and mussels. Do you think this could be an allergy?
