Oral allergy syndrom: Oral allergy syndrome (oas) is a type of allergy that occurs in response to contact with food allergens. Some times the allergy is caused by allergic antibody (ige) , some times it is not. Either way, if symptoms are reproducible with each repeated exposure, then you have a food allergy. There is a risk that oas could change or evolve into a more serious reaction such as anaphylaxis.
