No, once your symptoms are gone you may choose to stop. However many people find that the cause of their symptoms is their lifestyle: sitting, stress, and repetitive activities (eg. lifting, golf). Many people find that their regular Chiropractic adjustment helps keep up 'spinal fitness' (just like going to the gym keeps up body fitness and routine dental check-ups keep the teeth healthy) and then they are able to keep them doing the things they love for longer. How often you want to be adjusted is up to you.
