i hurt my arm quite badly one time. i did go to the doctor and they said nothing was wrong with me. when it still hurt quite badly 2 weeks later, i went back. 'oh yeah, this is broken. why didnt you come in earlier?'

my sister also had a broken arm. not only did they say it wasnt broken, when she went back the second time they 'discovered' that the wrong arm, which was perfectly fine, was broken!
