This is a weird story.
I went to my GP today because I was violently coughing last night and thought I had coughed up blood. Turns out the reason I was coughing was because I was actually choking on a small bit of the tomato sauce on top of the pizza tha I had for tea. Somehow I had inhaled a small bit and it got into my lung tube-thing staying there for a while.
I feel like a complete doofus.
