8Hoarseness
In addition to wheezing, hoarseness can be a sign of post nasal drip. It is a change in vocal loudness, pitch, or quality that can be barely noticed. This problem occurs when excess mucus builds up in the throat and interfere with the usual vibration of your vocal cords. More specifically, the accumulation can make these parts become paralyzed or prevent them from closing properly. In more serious cases, hoarseness can be pronounced with a hardly audible sound.
