Seriously I am lucky and have never in my life had back issues.
I think it would be a difficult delimma for me if I needed one. I'd probably just go to a physical trainer or massage therapist. Fortunately I am Mighty!
I knows lots of people who go to back crackers regularly...and thus point.
We have to see our normal doctors every year also for a checkup and or adjustment of our daily meds. Very few of us don't take any meds. So really, there's no difference.
I hurt my back bending and twisting over the wrong way in a tiny crawl space while I was cleaning air ducts and the back pain was terrible. I couldn't work. I made my first visit to a chiropractor who's been in the field of it for over 30years. No X-rays, or anything like that was done. I just filled out a questionnaire describing the pain and he adjusted the spine. I made 3 other visits until the pain was gone. That was over a year ago, and I haven't had the need to go since then
Chiropractors are very similar to Carpet cleaners in the public's eyes of their assumption of the quality of the services. Most people (who've never experienced the service) think of a yellow van pulling up in the driveway, charging just $99, and over wetting the carpet with a 3day dry time. Chiropractors have the image of someone getting behind you and picking you up to "pop" your back. It's much more professional and accurate than a pill pushing doctor charging you over $100 for a 10 minute visit.
That's just my experience with a chiropractor.
