Spring is here, and so is the pollen! Did your doctor tell you that you are allergic to trees, grass, or weeds pollen? You're used to the usual symptoms; breathing problems, sneezing attacks, and teary, itchy eyes. But then you notice that some fresh fruits, vegetables, and tree nuts are starting to cause an itchy mouth, scratchy throat, itchy ears, and swelling of the lips, mouth, tongue, and throat— even when there is no pollen around? You may have something called oral allergy syndrome.
