Hello. For a week now I have been having productive cough. During the first few days, I was feeling lethargic and I was coughing a lot. Then the lethargy went away and I coughed less (about 3 days in). But then I started coughing up small amounts of blood with sputum, about once a day. Then the cough almost went away and I started having a runny nose which turned into congestion and now something like a sinus infection. I still get the blood in sputum about once a day. It's been 4 days now.
