Hi all...
About 3 days ago I got a real bad sore throat and its getting better, but for the last two days I wake up and I cough once and my mucus is thick with blood in it. It only happens in the morning and then i am fine the rest of the day. I am a smoker and about 3 years ago I had an infected lung.... which was easily fixed with antibiotics.... what can be causing this? I have no other signs of a cold and i am getting regular headache but i have had that my whole life ... any info will be appreciated ....
