Allergy season is back with a vengeance. It's a feeling that some people know too well: stuffy nose, itchy eyes and a headache. But for those who say their allergies feel worse this year, there may be a reason why. Micaela Petrucci, 25, of Canton, said her allergies are a real annoyance this year. "I was just outside to try to read, and I had to come in because I had to blow my nose 3 times," she said. Petrucci said her eyes are so heavy and itchy, it makes her job more difficult, which entails long hours of staring at computer screens.
