Completely! As long as you’re not bleeding, concussed and/or in excessive pain that might be served better by going to urgent care or emergency department. For small fender benders up to medium accidents, it is most likely safe to get an adjustment. Provided the doctor will do appropriate neurological and physical checks before any treatment, a safe and cleared adjustment would be beneficial.
In an accident, our bodies could be jostled in many directions and cause joints to stick, muscles to tense up, pulling bones in various directions. The sooner that those are addressed, the sooner the body can relax and return to its normal state without losing any mobility during recovery. It’s a signal to the body that the harm/danger is over and that it can physically relax to recover.
