What are the symptoms of a seafood allergy?

Seafood allergies cause many of the same skin and respiratory issues that other allergic reactions usually produce. Hives and rashes are common, as are breathing issues. Similar to other food allergies, digestive issues such as pain, diarrhea and an upset stomach are regular. Seafood allergies also often bring swelling, which can occur in and around the mouth, on the face and elsewhere on the body. In rare cases, a seafood allergy can become a serious anaphylactic reaction, which makes breathing difficult.

It's a good idea to tell your physician about your seafood allergy symptoms. They will be able to determine whether you have a true seafood allergy or accidently ate some "bad" seafood—that which might not have been cooked properly or was left out too long. In addition, your doctor may be able to determine if you have only a fish or a crustacean shellfish allergy. If that's the case, you might have to give up your favorite finned fish but may still be able to devour those crab legs.
