I sort of expect it to be a lot worse than it actually was and in fact I think that I was pretty much afraid of laying down on the table at that Concord chiropractor office. It is not something that you should do without thought or careful research however, although I sort of suspect that it is necessary for you to know the difference between what is real and what is fake on the internet. You really have to suspect that anything you find on the internet is going to be motivated by profit after all. It is not as though the chiropractor is going about this for the fun of it or because he wants to be nice to his fellow man. They are running a business and a bad chiropractor is going to very motivated to tell you what it is that you want to hear about him. A good one will be happy to let his clients testify on his behalf I would think.
This is serious business, although the real danger is when you have a neck issue. In that case I am not really sure that this what you want to do, since they can actually kill you if you get really unlucky and the guy makes a real serious mistake when they are trying to get the vertebra where they are supposed to be. That is why you should be scared, but I suspect that there are rather few really serious issues. You will hear about the bad things obviously, while the people who have a good experience are not all that newsworthy. This is not where you sell papers or get people to click on the links to your web page of course. However it is something that you need to think about before the fact.
