'Ouchless' Shots
Instead of poking you with one needle, your doctor may soon stick you with 400 needles. But, believe it or not, this new "shot" wont hurt a bit!
Your doctor might stick a patch full of needles (below, right) onto your arm. Luckily, the short needles don't reach far enough to touch any nerves--cells that tell your brain that you're feeling something. So you don't feel a thing.
Then, the doctor removes the patch and applies liquid medicine to your "holey" skin. The medicine seeps through the tiny holes into your blood vessels--tubes that carry blood throughout your body. Scientists are still testing this idea. Maybe in about five years, going to the doctor won't be such a "pain"!
