question: I have been constantly choughing for about a month now. At first i would cough up alot of phlem but it was less and less everyday, but i am still coughing and i have sort of a stuffy/runny nose but not really. But when i do blow my nose there are black streaks in the mucus. Other than that i feel fine, no weakness body aches sore throat or anything. I've been taking dayquil but it hasn't gone away it's WAY better than before, but NOT gone. Is there anything i can do to take care of this AT HOME?
