Why do allergies cause that stuffy nose feeling?

Nasal congestion, or a stuffy nose, is a common and bothersome nasal allergy symptom. Congestion occurs when the immune system releases chemicals in response to an allergen. This causes the blood vessels inside the nose to swell, which in turn causes the lining of the nose to become swollen.
