If you have lower back pain, you know how much it can affect your daily life. You may feel shooting or stabbing sensations. They may start in the lower part of your spine, called the "lumbar" spine, and travel down through your legs. This can keep you from being active. But finding the cause of your pain can be tough, because many problems can trigger it. A chiropractor can find out why you are hurting, and can help give you relief.
