Depends on cause: Post nasal drip is from acid reflux, too dry saliva, retained throat secretions because the pharynx can't clear them, pharyngeal diverticulitis, foreign body sensation from globus, habit, chronic nasopharyngitis, and others. It rarely indicates a serious condition but i would be most concerned if there is coughing or choking with swallowing, hoarseness, or abnormal swallowing. Know cause to treat.
