I recently was in the hospital for 2 weeks.
I was scootering, And I was lip-sliding (w/e you call it) a bus bench, And I slipped and fell hard on my knee. I couldn't get up after that. I happened to tear my cartilage, and managed 2 staph infections in the cartilage and my upper joint in my chest. It's so weird a biker got a staff infection where I exactly got, and he died. :/
The pic:
I'm guessing all the redness is from the staph infection.
I'm still healing right now, getting better!
