@spider109 A mucus plug in my experience is different than the clear, thinner mucus that I typically bring up after/during my nebulizer treatment and airway clearance. In my experience they are small, pencil-eraser-sized and thick yellow -or- yellow/brown globs. I think amount, color and viscosity is likely different for everyone.

In a CT scan or x-ray, they appear as opaque areas in the airways and sometimes are referenced as airways that show impaction or are 'impacted'.

Have you spoken with your doctor about the amount of mucus you're producing and whether respiratory therapy with postural drainage and percussive cupping might help get some of that out of your lower airways?
