a few years back I had an operation on my leg because they had "found an infection on my femur" femur being the big bone from your ass to your knee
they made a drill go down from my ass to my knee, trying to clean it up... I got a huge scar
turns out they never found out what was wrong, and what that "substance" which they thought was an infection really was, and I still get sharp pain to that leg on some occasions
what about you? what's your story?
