Ear Nose | Otorhinolaryngology | Runny Nose or Nasal Congestion (Symptom)
Nasal congestion or stuffy nose is a term commonly used to refer to the obstruction to airflow in and out of the nose while nasal discharge means a discharge (fluid) from the nostrils. Both conditions are associated with inflammation and swelling (congestion) of the inner lining of the nasal passages and sinuses.
A viral infection (common cold) is the most common cause of nasal congestion and / or runny nose, but allergies, flu, sinus infections and can also cause these symptoms.
Less commonly, anatomical obstructions (such as a deviated septum, foreign bodies) can lead to nasal congestion. Other causes of nasal congestion or runny nose include environmental factors, hormonal changes, and some medications.
