A chiropractor checks your spine to see if you have any misalignments. Your spine is meant to be in line. When you have a misalignment, your spinal bones create havoc with your nervous system. This havoc and interference disturbs the mental impulses flowing from your brain to your body and body back to your brain. Your brain then can no longer keep the body healthy due to this interference. As a resul this can cause lack of vitality, weakened immune system, arthritis and other diseases.
