Since November I have been coughing up (1-3x a week) a thin, white (worm shaped) thing. It s very stringy and rubbery. Comes out in a ball and in my hand I can straighten it out. I always have lots of wheezing leading up to it. Some nights I am silent, other nights my chest sounds like Rice Krispies. I ve seen a doctor and they did x-rays and said there s nothing. It s clearly not nothing. I also have had LOTS of mucus come up for years, especially in the morning. White and foamy, then clearish. Once it s out, it s typically out for the day. These new white things have me concerned. She seem fleshy somehow.
