Here are some of the torture devices from my youth. The first is the original finger-poking lancet device that they gave diabetics back in the day. Imagine giving this to a kid and telling him to press the bright Warning-red button and release the spring-loaded needle towards his fingertip.

Then there was the Medi-Jector, pressurized needle-less hypo. Being a Star Trek fan, I thought this would be way cooler than taking shots. No. It was horribly painful and felt like you were stabbing yourself whenever you'd shoot up. You can't see the red release button that you'd press to shoot out the insulin. It looked like something the President would press to launch all missiles. I still have this thing around somewhere. The only thing it was ever good for was shooting my friends with high pressure, needle-thin streams of water, or insulin. Insulin smells horrible, btw.
