My chiropractor mainly specializes in kinesiology so it is actually very rare that he cracks my back. It is mostly muscle groups and tension and resistance moves that he uses. It is really awesome. It always amazes me how different parts of the body are connected.
I need my back to be clicked as it is bone on bone. If he doesn't do it I have to come back to relieve the pain. I normally do it myself but every now and then I need his help.
