Hi Stephanie,
I use to notice that my mucus would move when I'd get a massage. So, I started asking my husband to press on certain plug spots, really deep and hard, and rub around the area, at home when I was congested. I was amazed to see that it actually moved the mucus, sometimes even better than chest PT. Now whenever I have a major plug we do this and though it may take a good 10 to 15 minutes just in one spot, it works. Maybe a family member can try this for you?
Also, when I'm in the hospital I LOVE doing saline mists. They make everything in my lungs so moist. Sometimes I do two or three at a time.
Hope you feel better.
