I use the Wahl handheld massager, and also a vibrating bolster I found at Walmart. An hour of exercise a day helps, but I get more mucus up in the evening by using these tools. My imaging report said "scattered areas of bronchiectasis in all five lobes" - so I move these massage tools around my chest and back - while watching TV. It's good to get rid of any mucus I can, especially before going to bed.
