Chiropractic adjustments rarely cause discomfort; however, patients may sometimes experience mild soreness or aching following treatment (as with some forms of exercise) that usually goes away within 12 to 48 hours. If any discomfort remains for more than a day or two, be sure to let your chiropractor know. Keep in mind that such soreness can be a positive result since the chiropractor is restoring normal movement to an area of the musculoskeletal system that has not been functioning properly. The previously unused muscles can become briefly sore from their new, and proper, use.
