Laryngitis is an inflammation of your voice box (larynx) from overuse, irritation or infection.
Inside the larynx are your vocal cords — two folds of mucous membrane covering muscle and cartilage. Normally, your vocal cords open and close smoothly, forming sounds through their movement and vibration.
In most cases laryngitis symptoms last less than a couple of weeks and are caused by something minor, such as a virus. Less often, laryngitis symptoms are caused by something more serious or long lasting. Laryngitis signs and symptoms can include:
Weak voice or voice loss
Tickling sensation and rawness in your throat
You can manage most acute cases of laryngitis with self-care steps, such as resting your voice and drinking plenty of fluids. Strenuous use of your voice during an episode of acute laryngitis can damage your vocal cords.
