Hi, and thank you for letting me become part of this group...
Question:  I seem to have a knot of phlegm in the back of my throat which is almost constant.  I only use Stiolto Respimat inhaler (2 puffs in the am), and a rescue inhaler.  My PCP said to try Mucinex, did nothing.  My Pulmonologist says it’s a nasal drip?? Any ideas??  
Thank You..
