over the past few weeks I've been coughing up
a lot of phlegm which is multi-coloured (clear, yellow
, orange and green) and I went to see my doctor who diagnosed me with bronchitis, and prescribed me anti-biotics, which it turns out I'm allergic to, so I've stopped them. the phlegm occasionally contains streaks of blood through it, varying in quantity from the tiniest speck to quite thick
streaks. I'm an 18 year old smoker by the way.
