Anyone's LO have food allergies?

We tried green beans last night. She's done really well with sweet potatoes, carrots and peas. But after the green beans (3 tiny bites) she threw up. Not a large amount but definitely green beans. About 20 minutes later she was screaming. I've never heard her scream like that. Arching her back and turning so red. Obviously, going to talk to her doctor about possible allergy. (Hopefully it was bad gas.) But has anyone else dealt with allergies so far?
