Laryngitis is an inflammation of the larynx or voice box that can be caused by viral or bacterial infection, chemical irritation, or vocal overuse. Common symptoms include hoarseness, coughing, throat pain, and difficulty speaking or swallowing. Acute laryngitis lasts less than 3 weeks and is often caused by viruses. Chronic laryngitis produces lingering hoarseness from long term irritation or misuse. Treatment focuses on voice rest, inhaling steam, cough suppressants, and sometimes short term steroids or antibiotics. Voice therapy can help restore normal voice quality and prevent future issues.
