Possibly: Nut allergy usually comes on fast and furious and thus if she has survived the time you spent posting this question, it is likely not that serious. Note that she may not be allergic to all tree nuts and thus you should consult an allergist about this. In the meanwhile, be sure to have an Epinephrine kit (2 pack) on hand- this will ease your anxiety and may save her life some day. ...Read more

I was diagnosed with a cashew nut allergy as a small child, will i still be allergic 20 years later?

I was diagnosed with a cashew nut allergy as a small child, will i still be allergic 20 years later?

Probably: Only about 10% or less of people with nut allergy actually "out grow" it. If the reaction was very severe, it is less likely. Since there is a small chance of not being allergic, an allergy skin test and blood test to cashew would be one way to assess if sensitivity is still present. An allergist can assist in the diagnosis and interpretation of these tests. ...Read more

I have an itchy throat after eating cashews, what could be wrong? What are the chances of it itchy due to nut allergy?

Extremely high risk: Itchy throat is highly suggestive of a food allergy, and the next exposure could lead to worse symptoms (swollen throat and inability to breathe). So, definitely eat no more nuts of any kind until tested for allergy. If your are having symptoms now, get medical help if you feel swelling in the throat or tongue. This is an appropriate use of an er if necessary. ...Read more

Possibly: Stomach upset and vomiting after eating nuts are possible signs of an allergy. It can happen within minutes to hours. It very well could be unrelated to an allergy too. It's not unreasonable to try another exposure to cashews and almonds individually and see what your reaction is. Please, seek urgent help if you develop breathing issues, severe pain, swelling anywhere or lightheadedness. ...Read more

They said I could possibly develop a nut allergy one day. Why?

Risk of nut allergy: You can develop a nut allergy at any time in your life. Having a family history of allergy, or a personal history of other allergic disorders, such as eczema or hayfever may increase your risk of developing a food allergy.
