Q:	What can aggravate sinus congestion?
A:	Smoking, alcohol and damp weather can aggravate congestion. Diet can play a role as well. Excessive dairy products and carbohydrates may produce excess mucus.

Q:	What is swimmer's ear?
A:	Swimmer's ear is an itchy, painful infection of the external ear canal. After long periods of swimming and diving, water can get trapped in the ear canal. The ear canal can then become inflamed and swollen. This can soften and break down the skin lining, creating a perfect environment for bacteria to breed.

Q:	What are some allergens that can cause nasal congestion in an allergic response?
A:	Some common allergens such as pollen, grass pollen, dust, mold and some foods can trigger nasal congestion as an allergic response. When the mucosal lining of the sinuses becomes congested, discomfort such as pain and inflammation may result.
