is an inflammation and/or infection of
the mucous membrane that lines the
larynx and vocal cords. It can be acute
laryngitis, which accompanies infections
of the upper respiratory tract or
chronic laryngitis due to recurrence of
the acute form. The symptoms include
hoarseness of voice and loss of voice.
There may be a sore throat and
difficulty in swallowing or a feeling of
a lump in the throat. The usual cause is
a viral infection, although laryngitis
is bacterial in origin. Allergies that
produce respiratory symptoms, excessive
straining or use of the vocal cords may
also cause the condition.
