Your nervous system controls and coordinates all the functions of your body. If you interfere with the signals traveling over nerves, parts of your body will not get the proper nerve messages and will not be able to function at 100% of their innate abilities. In other words, some part of your body will not be working as well as it should be and sometimes that can have symptoms like pain, neck pain, back pain, bad posture, muscle weakness and more. Doctors of Chiropractic are the only profession trained to locate and remove subluxations.
