(HealthDay News) - Laryngitis occurs when the larynx -- which houses the vocal cords -- becomes inflamed. The results are hoarseness or loss of voice.

Here is additional information about laryngitis, courtesy of the U.S. National Library of Medicine:

• Most cases of laryngitis are caused by a virus, which cannot be treated with an antibiotic.
• In rarer cases, laryngitis is caused by a bacterial infection.
• Other causes may include allergies or an injury to the larynx.
• In addition to loss of voice, other symptoms of laryngitis may include fever, swollen lymph nodes, or swollen glands in the neck.
• To help vocal cords heal, try resting your voice.
• Use a humidifier to soothe a scratchy sore throat.
