I have it all too. CVA typically bothers me during allergy season.

Vocal cords get burned by stomach acid if you have GERD. My ENT told me the take some Mylanta liquid before bed.
Excessive mucus is your body’s way of protecting the vocal cords…

Of course, when I have a post-nasal drip and it makes me cough, I put Vicks vapo-rub on the BOTTOM OF MY FEET with socks.

These are the things I do, hope they help you.
