I'm getting a bit worried here. So, about 10 days ago, I had a viral fever and a cough. The fever went away, but this cough is still sticking around. And every morning, I'm noticing that I'm coughing up some orange mucus. I used to be a smoker but quit recently, though I still smoke occasionally. Should I be concerned about this cough and the orange mucus, or is it just part of the healing process? What should I do?
