What are some signs that you have a shellfish alleregy?

In brief: Itching, hives etc.

A shellfish allergy can be seen with tongue swelling or itching, cough, hives on the skin, and generalized pruritus that can occur after ingestion of shellfish.
In serious allergies, anaphylaxis may occur, with respiratory compromise and hypotension (low blood pressure)which can sometimes result in death.
