I spent about a day or so looking around and doing my due diligence before I picked out a chiropractor in Sacramento. Of course the more you know about how this stuff works, the more seriously you are going to take this task. You definitely do not want to blindly pick out the first guy that you see in the listings. From what I can tell it is not like there are lots and lots of people who get a bad result from going to see a chiropractor, but it happens and as with doctors there are some bad ones that cause most of the issues. The job involves trying to move the vertebra and other bones around in the body. The obvious thing is that you want them all to end up in proper alignment with one another, but you have to use a certain amount of force to accomplish that goal. So long as you apply the force properly there are no problems and everybody walks away happily. If you misapply that force, then perhaps one of the people involved leaves in an ambulance.
I know that this is something that has been building up for some time. I have had minor back issues ever since I got out of college. Some of it was from playing a couple of years of football. I was a linebacker until my knee went out. Of course they found someone to replace me while I was hurt and they did not offer me a scholarship when I was healthy. Some of it was probably related to me acting like a fool after drinking too much a few times. It was college and I did like to party when it did not interfere with progress towards my degree. It has just now gotten to the point of interfering with my life.
