My aunt is a physical therapist, and she does not recommend going to a chiropractor. Since they don't get the kind of anatomy of the body that PTs do, they really aren't safe to go to. They can really mess up your back. Go to a PT
Chiropractors can crack your back, do some physical therapy, and offer painkillers. In those areas, they are legitimate medical practitioners. Massage, chi alignment, and energy manipulation are scams.
