The fear of needles and razor blades goes back at least to the 1960's. The actual number of documented cases is very small, and the vast majority of those don't even involve injury. Follow up studies discovered that most of the reports turned out to be hoaxes perpetrated by the kids or parents (an older sibling playing a prank on a younger sibling, then getting scared when the parents found out and letting the parents report it as legit).
