Ear, Nose, And Throat Sponsors do not influence content. Most of the causes of laryngitis, such as common viruses or using your voice too much, are not serious. A few causes, however, require medical attention. Occasionally, you may develop laryngitis from bacterial infections and, rarely, from infections such as tuberculosis, syphilis, or a fungal infection. People with prolonged laryngitis should see their doctor to be checked for tumors, some of which may be cancerous.
Smokers are especially at risk for cancer.
Many times laryngitis may develop with, or a few days after, a sore throat. If these symptoms have been present for only a few days or occur immediately following an episode of using your voice more than normal, then the main treatment is to rest your voice as much as possible. Many people find inhaling steam, such as from a hot bath or shower, or a cool mist humidifier makes them feel better. In all cases you should avoid smoking and areas where others are smoking. Sometimes laryngitis may be more serious.
