Coughing is the body's way of removing foreign material or mucus from
the lungs and upper airway passages or of reacting to an
irritated airway. Coughs have distinctive traits you can learn to recognize. A
cough is only a symptom, not a disease, and often the importance of a cough can
be determined only when other symptoms are evaluated.

Coughs, Age 12 and Older.
A productive cough produces phlegm
or mucus (sputum). The mucus may have drained down the back of the throat from
the nose or sinuses or may have come up
from the lungs. A productive cough generally should not be suppressed; it
clears mucus from the lungs. There are many causes of a productive cough, such
A nonproductive cough is dry
and does not produce sputum. A dry, hacking cough may develop toward the end of
a cold or after exposure to an irritant, such as dust or smoke. There are many
causes of a nonproductive cough, such as:
Children may develop coughs from diseases or causes that usually do not affect adults, such
Many coughs are caused by a viral illness. Antibiotics
are not used to treat viral illnesses and do not change the course of viral

Sudden drooling and trouble swallowing can be signs of a
serious problem called epiglottitis. This problem can
happen at any age.
The epiglottis is a flap of tissue at the back
of the throat that you can't see when you look in the mouth. When you swallow, it closes to keep food and fluids out of the
tube (trachea) that leads to the lungs. If the epiglottis becomes inflamed or
infected, it can swell and quickly block the airway. This makes it very hard to
The symptoms start suddenly. A person with epiglottitis
is likely to seem very sick, have a fever, drool, and have trouble breathing,
swallowing, and making sounds. In the case of a child, you may notice the child
trying to sit up and lean forward with his or her jaw forward, because it's
easier to breathe in this position.

To use the bulb:
Don't do this more than 5 or 6 times a day. Doing it too often
can make the congestion worse and can also cause the lining of the nose to
swell or bleed.
