Saturday morning greeted me with some slight discomfort behind my knee. Upon examination, I saw a small, red, raised bump. I thought that perhaps it was a pimple, although sort of a weird place for one to appear. It's happened before, so I wasn't too concerned.
As the day progressed, especially in the evening, it was irritating me a fair bit more. On Sunday morning, it was bigger and a little redder, with some pinkish colouration encircling it. Maybe it's some sort of bite? Whatever it was, I was not going to let it stop me from playing a round of golf (beat my best score by 8 strokes, by the way).
By Sunday night, I was in some agony...and wearing long pants...without anything between my source of pain and the pant material. I stopped into a drugstore and bought some Neosporin with pain reliever, some gauze, etc. and bandaged myself up.
The sore in question didn't seem to get any larger today, but it has become a darker red...and the diameter of the surrounding pink circle has grown a little. It's not too terribly sore if nothing touches it and I can walk pretty well (like 90%), so I'm using this (against my better judgement) as reason for not visiting a physician over the matter.
I went and did some research online, first with the idea that what I have is some sort of bug bite. None of the pictures I found really tended to match up very well. I eventually hit on abscesses, and this seems to be the closest match, although I'm not entirely sure.
Like a damned fool, I went and looked up how abscesses are treated.
My tolerance for pain is minimal, I'm not ashamed to admit. Oh, please let it be something that resolves spontaneously!
...not my kind of luck. Will probably go in tomorrow if there's no improvement.
