Swollen Nostril

Top Reasons for a Swollen Nostril

The nose is often thought of as merely part of the physical appearance of the face, but in reality has an important purpose; a purpose that can be disrupted if you are suffering from a swollen nostril.  There are a couple of reasons for the condition that is largely preventable in most cases.

The Nostrils

Part of the respiratory system, the nostrils can be considered the external air filters of the body. Twin flaps of skin covered cartilage join the face over the septum at the top and along the inner cheeks.  As one of two air intakes for the body, the nostril filters and warms the air we breathe before it proceeds to the lungs.  The filtering process occurs through small hairs that grow from the anterior nostrils; as air passes through these small hairs, debris and airborne particles are trapped by the hairs and held until sneezed or blown out.

Because of the continuous flow of air brought in and discharged through the nostrils, the delicate membranes of the inner walls of the nostril can become dry.  Nasal secretions of mucus serve to keep these membranes moist the majority of the time, although there are a number of external and internal conditions that can alter this normal interior humidity.  Arid climates, cold weather conditions, medical conditions such as colds or allergies and certain medications can detrimentally affect the natural moist environment within the nostrils.


Few problems afflict the nostrils themselves.  The most frequent complaint is that of a swollen nostril, which could be the result of any one of several conditions including:

The cause of swelling of the nasal cavities may be as plain as the nose on your face.  If it is allergy season, or if the weather has turned extremely cold or dry, you may find that you need to help humidify the nose membranes.  Taking these precautions can help to avoid painful swollen nostril conditions.
