GraceB,
I actually got a copy of my CT scan and it confirmed "mild bronchiectasis." More on it here but the NIH does say Crohn's Disease predisposes one to it:

I took a look at the Aerobika breathing appliance and it seems more geared towards resolving mucus issues. My issues are primarily coughing and it is mostly dry (occasionally I cough up small amounts of mucus but it's mostly dry). So I am continuing with Symbicort inhaler for now.
