Exposure to latex or eating avacados cause asthma and swelling of my throat and mouth. Kiwi pinenapple and banana hurts my mouth like a burn and it peels. For years, I have also had situations where I have severe stomach pain, sudden vomiting, diarrhea, paleness and a alarming drop in blood pressure. It seems to be more severe as time goes on. Recently when this happened, I also had intense itching all over my body with a small raised, red rash. Could this be an allergic reaction? It has always resolved itself within an hour or so. I take Claritin 10mgx2 and singulair regularly with Benadryl when I have extra reaction. I've just never thought of the vomiting as allergy.
