Argh!

My lungs are hating me.
For the past fews days I've had a congested cough, but since I felt fine otherwise I sort of let it go (I know, I know, bad Emily).
Well, now I'm coughing pretty much once every few minutes and bringing up mucus plus (yes, sorry to be graphic). This is not good. It is also not good to hear things rattling around in the chest. Also getting chest pain and headache from all the massive coughing.
Not fun. No idea where this is going, either.
