Acid reflux is the most common cause of chronic laryngitis. But chronic laryngitis may be caused by more severe problems such as nerve damage, sores, polyps, cancer, or hard and thick lumps (nodules) on your vocal cords. The vocal cords are the vibrating elastic bands inside the larynx that produce your voice.
Laryngitis is inflammation of the larynx (voice box). Symptoms often include a hoarse voice and may include fever, cough, pain in the front of the neck, and trouble swallowing. Typically, these last under two weeks. Laryngitis is categorised as acute if it lasts less than three weeks and chronic if symptoms last more than three weeks. Acute cases usually occur as part of a viral upper respiratory tract infection. Other infections and trauma such as from coughing are other causes.
