In brief: Oral and Stomach
Typically shellfish allergy would cause itching, burning, stinging and/ or swelling of the mouth, tongue, or lips.
It may also cause stomach upset such as nausea, vomiting, cramping and possibly diarrhea. In some cases, it may cause a rash, shortness of breath, wheezing, coughing, and drop in blood pressure, or in severe cases death.
