"really stings" is an understatement. When my lower back was "out" once when I was a kid, my mom had me lay on the bed face down with a couple pillows under my hips. When it went back into place, I honestly wondered if I'd ever walk again. I thought she'd done me in. But within minutes I was good to go. (Oh how I long for the days when I could heal in minutes instead of days.)Yep. Sometimes a stuck joint being unlocked really stings for a moment but a few minutes later it's so much better!
My current chiropractor, who I think is a good one, does not use those little tapper things much except as an adjunct to significant pressure with his hands. I have to admit good results from a chiropractor that did use those tappers, but for the most part I always felt like they couldn't possibly make much real and lasting adjustment with such little applied power.
