My scabs appear to have disappeared after dealing with them for about 6 months. I was coughing a blood tinged scab up every 3 days - looked just like the pictures posted on this thread. We traveled to a state with high humidity for two weeks and they stopped. They never started up after returning home - it is getting warmer where we live so maybe that is why. Wondering if it is a dryness condition for me. Hoping they do not return!
