I think I am coughing up white fibers for the first time not to sure, what does this mean?. It started with a chest infection being very ill it is now 9 days later with improvement apart from a little chesty cough that tickerly feeling. Comes and goes sometimes surprises me especially out in public these are my spaz attacks humoring myself. Those days have gone where I worry. I see fibers more in my bedroom floating about especially near my computer as it acts like a magnet found that one out discovered a paper clip on my screen intrigued.
