Chiropractic has a very good history with symptom reduction. What we find is that roughly 80 percent of people obtain good results, 10 percent have SOME help with pain, and the final 10 percent have no appreciable change. Each person is different, and the doctor must work with this in mind. It is also advantageous to treat your injury sooner rather than later. Problems you have had for many years may take longer to treat as opposed to a recent injury. Remember, it takes time to effect a natural change in the body.
