Causes of Nasal and Sinus Problems
A chronic cough, facial pain, loud breathing, loss of sense of smell, and discolored mucus can all be signs that your child is experiencing a nasal or sinus condition. If these or other common cold-like symptoms last more than 14 days, a visit to a pediatric ENT -- a doctor who specializes in the ear, nose, and throat -- is recommended.
It may be that allergies or sinusitis, an infection of the sinuses, is to blame. Or your child may have a blockage in his or her nasal passage that is causing a buildup of fluid and pressure. This may due to:
Located in the very back of the nose and often called the third tonsil.
Soft growths that develop on the lining of the nasal or sinus passages.
Occurs when the wall that separates the nostrils is crooked.
Nasal or Sinus Tumor
In very rare cases.
