Here is where your lack of knowledge and experience with science/anatomy starts to show.
Your visit with the chiropractor, while it may have seemed beneficial, could have been nothing more than mere coincidence. Or, rather, he did something that either a masseuse or stretching/exercise could have done. Or, he actually did something unique.
All things point to coincidence/not-unique. If you can explain what a chiropractor can do that exercise or a masseuse cannot, then I may be inclined to listen. To beat a dead horse, a slipped disc isn't magically put back into place by a chiro or anything of that nature. Having the area massaged/stretched/rehabbed (via exercise/movement) is what helps a disc, outside of surgery. The chiro did nothing that was special or unique.
I'm sorry that you don't understand human anatomy & physiology well enough to know what is happening with your body.
