I was diagnosed with the flu (type a) on Sunday. I have a deep cough and this morning it hurts really bad to swallow. There feels like a large lump in my throat and when I tried to cough it up, it was dark green with a lot of fresh blood. The lump is smaller but still there.
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of lower respiratory tract infection(LETI) is more. LETI is common after flu infection. You are also having cough, phlegm and blood in sputum. So possibility of LETI (pneumonia) is high. So first get done chest x-ray to rule out LETI. If chest x-ray is normal than no need to worry about LETI. Sometimes cough cause friction bleeding. So you need antibiotic, antihistamine and anti-inflammatory Chat Doctor.  Do warm water gargles 5-6 times a day.
