Symptoms often start very quickly, within an hour of having come into contact with a nut, and sometimes within minutes. Reactions that take place more than four hours after coming into contact with nuts are unlikely to be an allergy.

Tree nut allergies are among the most common food allergies in both children and adults. The six tree nut allergies most commonly reported by children and adults are allergies to walnut, almond, hazelnut, pecan, cashew and pistachio.
Is Avocado a tree nut?

Can Allergies Be Cured?
No, but you can treat and control your symptoms. You’ll need to do all you can to prevent being exposed to things you’re allergic to — for example, staying inside on days when the pollen count is high, or enclosing your mattress with a dust-mite-proof cover. Allergy medicine can also help.
What are three symptoms of a food allergy?
They experience symptoms like swelling, rashes, hives, vomiting and, in rare cases, anaphylaxis. A non-IgE allergy usually has more gut-based symptoms like vomiting, constipation or diarrhea, as well as inflammation of the gut wall ( 6 ).
