Nasal congestion, or stuffiness, is typically caused by a swelling of the tissues that line the nose. Often the result of a cold, sinus infection or allergies, nasal congestion will frequently get better in a few days.
Decongestants and antihistamines may help by reducing the inflammation and slowing mucus production. Using humidifiers and saline nasal sprays can also provide some relief from congestion.
If nasal congestion does not respond to conservative treatment, prescription medications may be necessary. Only when this is a chronic, recurring condition will nasal surgery be considered to enlarge the openings that drain the sinuses and relieve symptoms.
