I used to have back pain (do a lot of standing and heavy lifting at my job). My mom started to work at a chiropractors office, and started getting her back adjusted. My mom also has a bad back, and in the past would throw her back out to the point where she couldn't move. Hasn't happened since she has been going to the chiropractor.
So I start going, figuring what the hell. From day one I have felt a ton better. Back is in better shape, I really don't get sick anymore, have more energy, and when I do a lot of strenuous activity my recoup time is a lot shorter. Best money I have ever spent.
