Your spine houses your spinal cord. The spinal cord transports messages from your brain out the nerves on each side of your vertebras (24 bones in your spine). Those nerves control everything in your body. Different nerves going thru different bones controls different things. If your spine is subluxated (misalligned) the bone puts pressure on those nerves not allowing the messages to get through properly. You may not even "feel" that your subluxated. You will need to see a Chiropractor in order to find this out.
