👃 Why does one nostril always feel blocked, even when you don't have a cold?
Sometimes, it's completely normal.
Your nose has a natural process called the Nasal Cycle, where airflow alternates between nostrils every few hours.
But there's an important difference between a normal nasal cycle and persistent blockage on the same side.
It could be associated with:
🔹 Deviated Nasal Septum (DNS)
🔹 Enlarged nasal turbinates
🔹 Nasal polyps
🔹 Chronic sinus inflammation
🔹 Allergic rhinitis
⚠️ If the same nostril remains blocked, particularly with recurrent nosebleeds, facial pressure, or reduced sense of smell, don't ignore it.
The key is to identify the underlying cause rather than simply treating the congestion.
👨⚕️ An appropriate examination can help determine what's affecting your nasal airflow.
📌 Save this post for future reference and share it with someone who frequently experiences nasal blockage.
