What Causes the Sneezing and Wheezing?
Some of these allergens cause sneezing, a runny nose, itchy eyes and ears, and a sore throat. Other items on the list, such as foods, may cause hives (a red, bumpy, itchy skin rash), a stuffy nose, stomach cramps, vomiting, or diarrhea. Less often, allergens can cause breathing problems like wheezing and shortness of breath (asthma). Some allergens, such as foods, are a problem all year long. But others might bother people only during certain seasons. For instance, you might be allergic to pollen from trees, which is present in the air only in the spring.
