Coughing and clearing throat

[Labinma]

Hi all, once again a non communicative husband with average to a above average progression, first diagnosis 2014 is now overheard coughing and clearing throat. May I gently inquire if these are signs of bigger symptoms to come? If so what could those be? Thank you. Lab

Not necessarily, but you're the one if it's allergies or a cold.

Have pft's been checked recently?
