Yes, it is generally a good idea to have a follow-up visit with a doctor after a car accident, even if you don't think you were injured, you think your injuries healed or your injuries were minor. A follow-up visit can be a good opportunity to ask the doctor any questions you may have about your health and recovery. Moreover, having a record of a follow-up visit can be helpful if you need to file a car accident lawsuit, as it can provide evidence of the injuries you sustained in the accident.
