The most common nasal symptoms include nasal obstruction/congestion, rhinorrhea (runny nose), and decreased sense of smell.

Nasal obstruction can be due to deviation of the nasal septum, which is most effectively treated with a surgical procedure called septoplasty.  Obstruction may also be caused by hypertrophy of the nasal turbinates which are normal structures within the nose that serve to warm and humidify air before it reaches the lungs.  Turbinate hypertrophy may result from uncontrolled allergies as well as long-term use of nasal decongestants.  Surgical reduction of the turbinates is an effective treatment for this condition when medical treatment fails.

Rhinorrhea is often associated with allergies.  The use of topical nasal steroids as well as oral antihistamines can help alleviate this problem.
