I have had these coming out my nose after sleep and using hydrogen peroxide in the back of my nasal cavaties. In addition I am coughing up about a teaspoon of brownish phlem every morning, and sometimes at night when sleeping on my back I will choke , wake up and cough up the same as the morning awakening.I have several pictures but not quite sure how to upload them all in a slideshow..here is a link (I hope)
