Laryngitis is an inflammation of the larynx, which is the part of the throat that contains the vocal cords. This condition often results in a hoarse voice or loss of voice, and it can be caused by infections, overuse of the voice, or exposure to irritants like smoke. Symptoms of laryngitis may include a sore throat, dry cough, and difficulty swallowing. Most cases are temporary and can be treated with rest, hydration, and avoiding irritants. If symptoms persist for more than a couple of weeks, it is advisable to consult a healthcare professional.
