Inflammation and a buildup of mucus in the chest can cause unpleasant symptoms like wheezing, sleep difficulties, and a sore throat. Congestion is also often accompanied by a cough that brings up phlegm.
Some mucus in the chest is normal, and having excess mucus from occasionally is usually not a cause for concern. However, if a person regularly has an uncomfortable amount of chest congestion, or if it is accompanied by other symptoms, they should see a doctor.
