Sinusitis / Sinus Infections

What is Sinusitis?

Sinusitis affects millions of Americans each year.  It is a highly symptomatic condition that has a dramatic impact on quality of life.

Sinuses are four pairs of hollow spaces found in the facial region around the nose and eyes. The sinuses include:

  • Frontal
  • Maxillary
  • Ethmoid
  • Sphenoid

Like the inside of your nose, sinuses are lined with a thin layer of tissue called the mucous membrane, which produces mucous. This mucous flows out through the openings of the sinuses into the nose. The mucous from our nose and sinuses is what helps protect us from pollens, pollutants, molds, dust and germs found in the air we breathe. When these openings become blocked, your sinuses may become infected and are often dramatically affected.


Anything that causes swelling in the nose can block the openings between your sinuses and your nose, including a cold, an allergic reaction such as hay fever, or a reaction to some chemical to which you've been exposed. The blockage causes air and mucous to become trapped within the sinuses, which may trigger painful symptoms. 

Symptoms of Sinusitis

The most commonly experienced sinus-related symptoms are:

  • Nasal discharge (drippy nose or drainage down the back of the throat that may or may not be discolored) 
  • Congestion
  • Lack of energy/fatigue
  • Headache
  • Facial pressure or pain
  • Sore upper teeth
  • Inability to breathe through one or both sides of your nose
