Chiropractic is more than just treatment of pain symptoms: chiropractic is about optimizing your health in general.
The nerves that control EVERY function of the body originate in the brain and travel through the spinal column. They exit the spinal column through little holes called foramina. When the spine is out of line, what we Chiropractors call a "subluxation", the foramina gets smaller, making it harder for the nerve to pass through. When this happens, our body doesn't receive 100% of the messages from the brain and dysfunction and disease occur. When this first happens, we don't normally notice any symptoms. By the time symptoms,such as pain and stiffness, are noticeable, the problem has been occurring for some time and significant damage has occurred to your body's tissues. That is why it is important to get your spine checked even when you are not in any pain!
By keeping yourself in the proper alignment, you are less likely to develop symptoms and have an overall healthier body!
