I broke my back in '91. The MRI showed scar tissue all around it and it was badly calcified indicating that I had broken it previously and never knew it....it had just scarred itself back together.
The neurologist said that I needed a fusion. He told me that the chance of the fusion making things better were about 20%, the chance of it making things worse was about 20% and the chance that I ended up right where I was, was 60%. I also had two bulged discs that were also complicating things. I chose to do nothing figuring, it had healed once, it would probably do it again.
What followed was 6 months of the worst pain I have ever had and 2-3 days a week of PT. I finally gave up on the PT and decided to try a chiropractor. This P'Od my mother who was an old school nurse and hated DOs and chiropractors. My mother told me that chiropractors work on the premise that they get you feeling a little better and then tell you that they need you to come in weekly for the rest of your life (she wasn't completely wrong from what I've seen).
I saw an add in the paper of a brand new chiropractor in the area who was absolutely beautiful so, of course, I chose her. She was just as beautiful in person but, she was about 5 feet tall and weighed maybe 90 pounds. I am 6'2 and about 225 at the time and I didn't think she would be able to help me. She looked at all the images and said she thought she could help me.
I laughed and said words to the effect of "you can help me but it will take 2 visits a week for the foreseeable future right?". She then said, she could fix me in 12 visits or she couldn't help at all. I agreed and sure enough, in 6 weeks I felt almost perfect. I said thanks and walked out and I have never had a serious issue with my back since. I have tried chiropractors a few times since but, they all wanted me to come in regularly for "maintenance".
