Laryngitis
Also known as: Voice Box Inflammation, Hoarseness
Laryngitis is inflammation of the voice box (larynx) caused by overuse, irritation, or infection, resulting in hoarseness or temporary voice loss. Acute laryngitis is usually viral and resolves within 1–2 weeks. Chronic laryngitis lasting more than 3 weeks may indicate an underlying condition requiring evaluation.
