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.
