There could be a host of reasons for this ailment. If this problem is existing since a long time, then it could be an allergy. The symptoms that you are witnessing could be an indicator of Hay fever. Despite the name, it isn’t a reaction to hay and doesn’t cause a fever but is just a medical term. Other symptoms include an itchy mouth, eyes or skin. Many people experience it seasonally because they are sensitive to airborne mold spores and pollens from grasses, trees and other plants. Others experience symptoms year-round, caused by environmental allergens like dust mites, pet dander (tiny scales shed from animal skin or hair) and cockroaches. However, if you are experiencing a runny or stuffy nose and a fever, you may have a sinus infection. Sinus infections are caused by bacteria or viruses, not by allergies.
