Fall has arrived along with fall allergies. With the cooler temperatures and color-changing leaves also comes mold and pollen. According to the American College of Allergy, Asthma & Immunology, 40-60 million people are affected by allergic rhinitis, also known as hay fever. Common symptoms include sneezing, itchy eyes and stuffy or runny nose. Doctors must prepare for the influx of patients they will treat during this season.
