Nasal congestion, or a chronic "stuffy nose," is the feeling of nasal blockage or obstruction, often accompanied by increased mucus production. It is a symptom rather than a disease and can significantly impact a person's ability to breathe comfortably, sleep, and or engage in daily activities with comfort and confidence.
Diagnosing nasal congestion
Many cases of chronic nasal congestion are allergy-related. To identify triggers, various tests may be performed:
- Skin prick test: This is the most common allergy test. Small amounts of potential allergens are applied to the skin, typically on the forearm or back, using a gentle prick method. If you're allergic, a small, raised bump (similar to a mosquito bite) will appear.
- Intradermal skin test: If skin prick tests are inconclusive, an intradermal skin test, where a small amount of allergen is injected just under the skin, may be used.
- Blood test (Specific IgE): This test measures the amount of allergy-causing antibodies in the bloodstream, known as IgE. A sample of your blood is sent to a laboratory to test for multiple allergens.
- Patch test: This test checks for skin allergies and is used to identify substances that cause contact dermatitis, which can affect nasal passages if inhaled.
