Hay fever is the most common allergy in the U.S., affecting approximately 10% of the population, and often causes seasonal itching, sneezing and a runny nose.
Dr. David Lang is an allergist at Cleveland Clinic, he says cold temperatures and rain in the Midwest and north east through March and April have caused the spring tree allergy season to overlap with the summer grass allergy season.
Dr. Lang warns that once we get a few sunny, dry days, pollen counts will start to rise. He adds that it's important to take your allergy medicine regularly, not just on an as-needed basis.
