Chiropractors are primary health care professionals who use hands-on treatment techniques to restore and improve joint function, especially in the spine. During a first visit, a chiropractor will take a full medical history, examine the patient, and may order x-rays to develop a treatment plan. Common conditions treated include headaches, neck pain, back pain, and sciatica. Chiropractic care aims to reduce pain, improve mobility, and help the nervous system function properly.
