In brief: No and yes

A post nasal drip will not cause asthma but it certainly could cause you to have to clear your throat.
Everyone has a post nasal drip and it is only a problem when there is a change in either the quality or the quantity of the mucus. Once the cause of the change in mucus is treated the sensation of a post nasal drip should improve.
