==Overview==
'''Catarrh''' (commonly known as a "runny nose") is a discharge or [[mucus]] blockage caused by the swelling of the [[mucous membrane]]s. The symptom is usually associated with the [[common cold]], but can also be found in patients with [[otitis media|middle ear infection]]s, [[tonsillitis]], [[sinusitis]] or an [[adenoid]] infection. Some blockages may be chronic.
 
==Historical Perspective==
The word "catarrh" comes from the Greek "katarrhein": ''kata-'' meaning "down" and ''rhein'' meaning "to flow."
 
==Causes==
* [[Common cold]]
* [[Allergy]]
* [[Hay fever]]
* [[Rhinitis]]
* [[Sinusitis]]
==Natural History, Complications, Prognosis==
Catarrh can result in the inability of the [[Eustachian tube]] to equalize the pressure on the two sides of the eardrum resulting in pain and damage to the eardrum (barotrauma).
As a result of the inability to equalize the pressure, there can be a buildup of pressure around the eardrum which results in ear pain. As a result, catarrh can result in discomfort with changes in air pressure such as those that accompany:
*Elevators
*Airplanes
*Traveling at elevation
and other activities associated with a change in air pressure.
 
Even the shallow end of a swimming pool can be problematic to the person with catarrh in so far as [[barotrauma]] to the middle ear can occur in as little as 4 feet of water.
 
Sexual catarrh refers to a runny nose following sexual intercourse.
