hi there....i have had a horrible cold for the past 5 days and i can't seem to get rid of this cough. in the morning, i am coughing up green phlegm (sorry for being so graphic) with flecks of blood in it. it's very scary to me. i don't have health insurnce right now - i'm in transition. what do you think this is? could it be bronchitis? will it go away on it's own? i've been resting and drinking loads of fluids and i still feel crappy. help!!??
