I totally believe in good chiropractic methods!!! (Having said that, it all depends on the Chiropractor you get.)
I've had one that damaged me and have had three others that were terrific. Chiropractic methods are not all the same so you need to find the methods that work best for you.
Here is one small example of how they have helped me. I travel frequently by plane and started having terrible pains in my head every time the plane began its descent. I was like having a thousand pins in my eye and forehead. It became so severe that I became terrified with flying. I mentioned it to my Chiropractor who checked and adjusted the bone structure of my face and skull along with relieving the pressure behind my eyeballs. I have never had the terrible needle sensation again. I go to this Chiropractor every time before I fly.
That was just one small example. I could write a book on how they have changed my life for the better.
All that being said, let me also say, I grew up in a family that considered Chiropractors to be all quacks (I still think some are). I first went to a Chiropractor when I was in my twenties because I was running out of options.
