<human>: So this all began a week ago when I discovered what I thought were 2 warts on the top on my knee. I had never had any warts before but I had some friends that had and they said it looked like a wart so I thought, fuck it, I can get rid of these myself, no need to get any doctors involved. Big mistake. So I use some Compound W wart freezing stuff and it kind of hurts but its nothing too bad. They look so uneffected by it that I didn't put a bandaid on them and went to sleep. The next morning I wake up and even before I can pull the covers away I know something is wrong, I can feel my heartbeat in my knee. So I get up and I see that what had once been a harmless skin colored bump has transformed into a purple volcano with a puss crater in the middle. Being the stupid college student I am, I shrug it off as the wart just dying. I put a bandaid on it and continue on with my life.

It's been a week and I can no longer ignore the pain in my knee, so I go to the emergency room and explain what had happened. After taking a look at it they tell me that only one bump was a wart, the other was just inflamed scar tissue that I had managed to kill my freezing it and now might possibly be infected. So after some giggling from the nurse they proceed to cut everything out and stitch me back up. I left the hospital with 8 stitches and a knee brace because I didn't want to go to the doctor in the first place.

Summarize the given text in a few sentences.
