Why does one side of your nose get clogged up bad?

One side of the nose may become clogged due to several factors, including nasal congestion from Allergies, a cold, or sinus infections, which can cause swelling in the nasal passages. The nasal cycle, a natural process where one side of the nose becomes more congested while the other is less so, can also contribute to this sensation. Additionally, anatomical variations, such as a deviated septum, can lead to uneven airflow and congestion.
