When i was about 5 i believe, i had a bone infection in my knee. It HURT. A LOT. i couldn't walk at all, and i was really an active toddler. I was taken to my doctor who in return said i was faking and just wanted attention. i wanted to slap her for being such an idiot. she sent me to get an X-ray because we demanded something, so we went and saw nothing. the xrayppl told us to go to a psychologist. went there and they told us we needed an orthodontist FAST. we went and they did a special X-ray and found my knee had a sort of infection. i was rushed to the ER and they were afraid i had leukemia, and they did a bunch of tests. it was just a bone infection. They inserted a catheter and an IV and such, and i had to live with a tube sticking out of my chest for a week, since the antibiotics couldn't be taken by ingestion. to find out, they had done a knee biopsy. i was asleep and remembered nothing of it. only thing is when the procedure was over i flipped out and thought my parents weren't my parents. coulda been the dream i was having when i slept.
don't worry, you'll hardly notice.
