I had a cough for the past two years, mostly at night. I have tried everything. The ENT scratched his head and admitted he didn’t know. We finally found it was caused by my asthma. It was just a tickle in the throat that caused me to cough violently. He found that it was a type of asthma attack. I will bring this to his attention, as I am extremely allergic to mold.
I wonder if there might be a borderline situation with this mold that mimics asthma?? I have SEVERE allergies to mold (eventually had to move out of Louisiana, my home state, because of them), and I have a similar night cough, and some of the other symptoms noted on this thread, but never been diagnosed with actual asthma. My latest ENT thought it might be from “silent acid reflux”, but having tried elevating my bed and taking “proton suppressors”, and still having the cough, I, like you, wonder........
