Oral itching or even swelling can occur with nuts or fruits contained in the deserts. If these are the only symptoms, could be oral allergy syndrome (or pollen-food syndrome).

Some people with very mild allergies can use antihistamines alone, but everyone should have Epinephrine available. Unfortunately, there are no drugs that will prevent or resolve a food allergy so you can eat the food without risk, although this is an active area of research.

Positive or Negative: A positive skin or blood test for allergy to shellfish is enough evidence to diagnose an allergy if you have a convincing history of allergic reaction to shellfish. If the history is inconclusive, a blinded food challenge can be performed to help confirm the diagnosis. If you are diagnosed with shellfish allergy, you are at risk of a life threatening reaction. There is no test for severity.
