Wow, gosh El I'm so terribly sorry. This is not a nice situation to be stuck in & waiting.
I would however definitely have repeated XRAYS, especially after the summer & when the viscous allergy season has passed. This season is as you probably heard one of the fiercest allergy times on record. So who knows how much of what is irritating and perhaps exacerbating your lungs & cough.
When the lungs & heart get involved, I know oh too well the "hit" of seriousness one gets with an AI disease. It's a rough & scarey scenario.
But you're not alone.
We'll be here for you, thinking of you always & always for an ear.
Hoping you had a good salsa nite!
You hang in there.
Sincerely,
Erin
