What can cause congestion?
Nasal congestion occurs when the blood vessels in the nasal passages become swollen and inflamed. Common causes include:
- Common Cold: Viral infections often trigger congestion as the body's immune response leads to inflammation.
- Allergies: Allergic reactions to pollen, dust, pet dander, or certain foods can result in nasal congestion.
