Is it true that once you start seeing a chiropractor you have to go forever?

No. Cases that have been chronic for years without chiropractic care take longer to heal. Their can be so much damage and change to the area that it will require more care than an acute injury. It will take more than one visit to correct the problem. Once corrected and the Doctor feels it is stable enough, they will be able to decrease the frequency of visits. The goal is to get checked regularly to prevent future problems from occurring. Its like going to the dentist and getting your teeth checked, you go to prevent cavities and other problems.
