I believe I have had it for many years. To be honest, whenever I am handed a new diagnosis, I spend /zero time "wondering where I got it" - all I want to figure out is the best way to get rid of it, make it better, or learn to live with it.

I have been prone to laryngitis my whole life, and never could sing worth a darn, even though I came from a family of talented vocalists. I grew up in an industrial neighborhood where the snow in the yard turned gray from pollution within a few days, we played on the debris piles of the factories, and as a youth I worked in some very questionable factory environments. Then we remodeled old houses as a side gig for years, and I always gardened.

I have no idea what the professionals think about cause and effect - I am just happy the speech therapist has found some exercises that work for me.

All that said, my Dad was a talented tenor, and he always taught us kid to be careful how we coughed, cleared our throats and used our voices so we wouldn't "damage our pipes." When I first started airway clearance, it was immediately obvious that I needed to learn the proper huff coughing technique or my vocal chords would be angry - especially since I was nebulizing levalbutero and tobramycin twice a day as well. (Before the days where 7% saline was commonly used)

Great question! One I plan to ask my cough clinic lead physician.
