It can help with a good number of things. But it doesn't help everyone, or with everything. I know people who love it, but I had it done, by a chiropractor, licenced in Chinese Medicine, for my chronic Migraine, and got no help at all. It hurt like shit, too. But some people get really good results from it.
I guess that would also mean that Chi energy either doesn't exist,or isn't helpful for anything as many people believe?
