Allergies are common. Heredity and environmental exposures may contribute to a predisposition to allergies. It is estimated that 1 in 3 people have an active allergy at any given time and 3 in 4 people develop an allergic reaction at least once in their lives. While symptoms are not life-threatening, the itchy, watery, red, puffy eyes and sneezing, nose itching, nasal congestion and post nasal drip can significantly affect quality of life. Other common symptoms are fatigue and cough. Symptoms range from mild to severe and from intermittent to seasonal to year-round. While there is no cure, allergies can be managed with a variety of treatments.
Sinus congestion may be a symptom of allergic rhinitis, or related to other problems such as nasal polyps or other tumors, overuse of nasal spray decongestants, acute or chronic sinus infections, or anatomical abnormalities such as a deviated nasal septum. When sinus problems persist, a correct diagnosis is key to finding the proper treatment.
