@tinaesims, Hi. I have to share this story because it stresses the importance of nebulizing saline. Here goes. I did my saline treatment this morning and coughed up the usual goo. But this time, I saw a small bit of bright red. So, I thought it was from a small lung bleed. Upon closer inspection, I saw that it was in fact, a small tiny bit of my bright red winter scarf that I had unpacked yesterday. I had even contemplated on getting rid of it because it sheds a lot of yarn onto my grey wool coat. Now, I am sure it has to go bye-bye. Now, what if I hadn't have coughed that up? Can you imagine the mucous plugs that can form when you do not clean your lungs out? My apologies if I grossed anyone out. But, you know how it is.
