Chiropractic was developed by Daniel David Palmer, a self-taught healer in Davenport, Iowa. Palmer wanted to find a cure for disease and illness that did not use drugs. He studied the structure of the spine and the ancient art of moving the body with the hands (manipulation). Palmer started the Palmer School of Chiropractic, which still exists today.

Sharp, shooting pains are mostly neurological false alarms about relatively trivial musculoskeletal troubles: your brain reacting over-protectively to real-but-trivial irritations in and around the spine. The brain takes these much more seriously than it really needs to, but evolution has honed us to be oversensitive in this way. That’s not to say that the brain is always over-reacting, but it usually is. Most of the time, a sharp pain is a warning you can ignore.
Chiropractors are not normally licensed to write medical prescriptions or perform major surgery in the United States,[62] (although New Mexico has become the first US state to allow "advanced practice" trained chiropractors to prescribe certain medications.[63][64]). In the US, their scope of practice varies by state, based on inconsistent views of chiropractic care: some states, such as Iowa, broadly allow treatment of "human ailments"; some, such as Delaware, use vague concepts such as "transition of nerve energy" to define scope of practice; others, such as New Jersey, specify a severely narrowed scope.[65] US states also differ over whether chiropractors may conduct laboratory tests or diagnostic procedures, dispense dietary supplements, or use other therapies such as homeopathy and acupuncture; in Oregon they can become certified to perform minor surgery and to deliver children via natural childbirth.[62] A 2003 survey of North American chiropractors found that a slight majority favored allowing them to write prescriptions for over-the-counter drugs.[38] A 2010 survey found that 72% of Swiss chiropractors considered their ability to prescribe nonprescription medication as an advantage for chiropractic treatment.[66]

The next step in the process was an X-ray. Having an X-ray done of your spine can help the chiropractor determine your treatment plan and can aid in the adjustment. That said, not all chiropractors will recommend an X-ray at your appointment. It turns out some chiropractors say that X-rays should be part of routine chiropractic care, while others argue X-rays aren't necessary for every patient. When researching potential chiropractors, feel free to ask if they recommend X-rays for all patients and how the X-rays can benefit your treatment plan.
Chiropractors use hands-on spinal manipulation and other alternative treatments, the theory being that proper alignment of the body's musculoskeletal structure, particularly the spine, will enable the body to heal itself without surgery or medication. Manipulation is used to restore mobility to joints restricted by tissue injury caused by a traumatic event, such as falling, or repetitive stress, such as sitting without proper back support.
