Doctor's Notes on Laryngitis
Laryngitis is inflammation and/or swelling of the larynx (also termed voice box). The most common symptoms of laryngitis include voice hoarseness or only able to whisper, feeling a tickle or slight irritation in the throat and the urge to clear the throat, cough and/or fever.
There are multiple causes of laryngitis. The most common causes are infections by viruses or stressing your voice. Bacteria can also cause laryngitis. Even after infection has resolved, laryngitis symptoms may persist for a few weeks. If laryngitis persists, the underlying cause could be cancer.
