Will repeated adjustments make my vertebra too loose?

No. Adjustments are only applied to the areas of your spine that aren't moving properly. Our chiropractic training and experience helps us identify which vertebrae lack proper function. As your treatment progresses you may find that your spine makes an occasional "pop"on it's own. This is completely normal as your spine is regaining it's proper motion and before supporting muscles have had adequate time to strengthen to control the restored motion.
