First, the responder who said chiropractors aren't doctors is wrong! Their title is Doctor of Chiropractic and their schooling is extensive! They spend as much time as an MD in school, just less time interning and more time actually practicing what they're taught. And their scope of practice is narrower, so they learn/know more about what they do overall.
I've gone my whole life and so have my kids. It's very safe and effective. Helps us get sick less often and be less sick when we are, because the spinal cord houses the nervous system, increasing the body's ability to heal itself and function at its highest level.
Exercises, stretches, and xrays are good. They are mostly taught how to read spinal xrays only so I'd trust them more than a radiologist because that's all they know!
At first you'll probably go three times a week, then two times, once, every other week, and then monthly for maintenance. Schedules are reduced based on pain level and objective findings. There are phases-pain reduction, retraining, then maintenance. I like to compare it to dentistry or the gym. You can brush your teeth everyday but still need to go to the dentist once in a while. And you can't expect to stay in shape if you don't exercise! I will go for life, because I will have a spine my whole life. And that spine will be subjected to carrying my kids, lifting, bending, twisting, car accidents, falls, etc. And because I want my body to function as best it can to handle those stressors!
Find one that makes you feel comfortable, that respects your limits financially, that does a good job. It's a rare doctor that treats you well when nothing is failing, that's the only time we see an MD. This way you'll stay well and need to seek actual help less, and stay healthier. Prevention is key! And not just masking symptoms, but optimizing wellness potential. I love my boss now, we work with patients' insurance, always cap their monthly payments, and allow people to walk in as long as they make it for all their visits that week. We are flexible, affordable, and all about working with you to make it work!
You're doing the right thing, and if they can't treat you, they will tell you. Ask lots of questions and you'll be fine! It's helped me and many people I know with back pain, headaches, allergies, colic, incontinence, neck pain, whiplash, arm/hand/foot/leg numbness, and many more!
