WARNING: Gross topic ahead. You have been warned.
I had been having lung issues after being sick with the flu (which was most likely H1N1, I guess) and had been coughing up bright red blood in the junk from my lungs in the mornings. This happened for several days in a row. I decided to finally go to the clinic Saturday morning. After the exam, they gave me some sample cups to collect what I was hacking up for three mornings. But wouldn't you know it, the following day and since then I haven't been coughing up noticeable amounts of blood. Isn't that how things always work? Anyway, I went ahead and did the collection these last three days and will bring the samples in just to see if they can find anything that I can't see.
I guess the lesson to be learned is not to procrastinate with stuff like this.
