I have oral allergy syndrome and can't eat nuts but used a body wash with walnut shell in it. Will I get symptoms?

Oral allergy syndrom. Oral allergy syndrome are local symptoms on contact with certain food due to cross reactivities of those to environmental allergens. It usually does not cause life threatening events like in real food allergies. You can test it on a small area on your skin before applying it to the whole body to gaze how much symptoms you get.
