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........
I blended a mixture of ice, honey, apple cider vinegar and garlic and started sipping on it.
I no longer have the condition but since have added large doses of Ester C and Vit. D.
I do not tout this as a cure because I have no idea. I only know none of the usual rememdies worked for me and I had bad reactions to cough medicine--I was a mess.
Acid reflux was an initial diagnosis, too. The only reason he gave me the Singulair was to help with my allergies. I was taking the allergy shots weekly and they were about to kill me. I was in bed most of the day. Now with the Singulair the allergies are better and the cough is gone!!
