Laryngitis is a relatively common clinical disease with a variety of symptoms and individual differences. Common symptoms include pain in the throat area. If the pain is severe and accompanied by noticeable swelling, it may affect swallowing and breathing, and could lead to swallowing obstruction and breathing difficulties. Another common symptom is hoarseness, especially seen in acute laryngitis, as it can cause congestion and swelling of the vocal cords, which easily leads to hoarseness. Generally, when symptoms of laryngitis appear, it is advisable to visit an otolaryngology department promptly for a laryngoscopy to assess the extent of the inflammatory response.
