GERD and LPRD can also cause swelling of the vocal cords and to the area behind the vocal cords, called the postglottic space. When your sinuses and GERD/LPRD are acting up, your vocal cords are getting hit from above (by the inflammatory postnasal drip) and from below (by the inflammatory acids coming up from the stomach).
