Laryngitis is inflammation of the larynx (voice box). In most cases, it gets better without treatment in about a week.
Symptoms of laryngitis can begin suddenly and usually get worse over a period of two to three days
Laryngitis is often linked to another illness, such as a cold, flu, throat infection (pharyngitis) or tonsillitis.
Laryngitis is only contagious if it is caused by an infection.
